Item 3.  Source and Amount of Funds or Other consideration.

On July 14, 2004, and effective as of June 30, 2004, Tenet Information Services,
Inc.  ("Tenet")  and Let's Go Aero Inc.,  Colorado  Springs,  Colorado,  ("LGA")
entered  into a  definitive  agreement  for  LGA's  shareholders  to  acquire  a
controlling interest in Tenet through a stock-for-stock  exchange.  All of LGA's
shareholders  will exchange all of their 2,640.93 shares of LGA common stock for
a total of  5,762,232  newly  issued  shares of Tenet's  $.001 par value  common
stock. The 14 former LGA shareholders  will then own in the aggregate 85% of the
issued and outstanding shares of Tenet.

Mr.  Drabczyk  obtained his 261,827 shares of Tenet through  exchange of his 120
shares of LGA and  obtained  196,371  options to acquire  Tenet shares of common
stock through exchange of his options to acquire 90 shares of LGA common stock.

Item 4.  Purpose of Transaction.

The purposes of the acquisition  were (1) for the former  shareholders of LGA to
acquire control of a public company that had no business  operations,  yet which
had some cash that could be used to fund operations of LGA, (2) to improve LGA's
ability to raise additional working capital, and (3) to provide an incentive for
holders of LGA  convertible  notes to convert the  approximate  $1.3  million in
principal and interest due on such notes to common stock. Mr. Drabczyk was not a
note holder.

The former  Directors of Tenet  appointed  Marty  Williams and Sara  Williams as
Directors of Tenet pursuant to the terms of the Acquisition Agreement, Stock for
Stock.  Marty  Williams  was  appointed  by the new Tenet Board of  Directors as
President,  Chief Executive  Officer and Chairman of the Board of Tenet and Sara
Williams was appointed as Secretary,  Treasurer and Chief  Financial  Officer of
Tenet.  Under the terms of that same  agreement,  Jerald L.  Nelson  and Fred J.
Anderson  resigned  as  officers  and  Directors  of  Tenet.  Eric J.  Nickerson
continued his position as a Director of Tenet.

As a result of the  exchange  of shares,  Tenet now holds LGA as a wholly  owned
subsidiary.  Therefore, Tenet has effectively acquired all of the assets of LGA.
Tenet will also move its principal office and business  operations to 3380 North
El Paso Street, Suite G, Colorado Springs, Colorado 80907.

Prior to the  acquisition,  Tenet,  as a result of the sale of all its remaining
operations on October 22, 2003,  was a publicly  traded company with no business
operations,  but  with  approximately  $200,000  in cash and  receivables  after
subtraction  of  liabilities.   Tenet  had  1,016,860  shares  of  common  stock
outstanding  at  June  30,  2004,  just  prior  to  the  effective  date  of the
acquisition.

LGA was a privately held company and is a product design and engineering company
based  in  Colorado  Springs,  Colorado.  It  develops  and  sells  novel  cargo
management  solutions for the  automotive,  recreational  vehicle and recreation
industries.

Item 5.  Interest in Securities of the Issuer

       Class: 6.6%

(b)    Shares  beneficially  owned includes options to acquire 193,371 shares of
       common stock.  The options expire March 31, 2006.  Mr.  Drabczyk has sole
       voting power and sole dispositive power with respect to all shares listed
       in Item 5(a).

(c)    See Item 3, above.

(d)    Not applicable.



(e)    Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to
        Securities of the Issuer.

Mr. Drabczyk is not a party to any contracts,  arrangements,  understandings  or
relationships with any person with respect to any securities of Tenet other than
as a consequence of the fact that he among all the other shareholders of LGA has
tendered  his shares of LGA to Tenet for  exchange  pursuant to the terms of the
Acquisition  Agreement  described  above.  Mr.  Drabczyk  is not a party  to the
Acquisition  Agreement,  but has executed a Subscription Agreement between Tenet
and him with  respect to the  exchange  of his  shares of LGA.  The terms of the
Subscription   Agreement   with  Mr.   Drabczyk  may  be  summarized  as  merely
representing  and  warranting  ownership  of the LGA  shares,  his  status as an
accredited  investor,  his  access  to  information  about  Tenet,  and  the  he
understands  that the shares of Tenet he will get in exchange will be restricted
securities. The only covenant in the Subscription Agreement is that Mr. Drabczyk
will not sell his Tenet shares unless they are registered or the  transaction is
exempt from registration.
