Read  Instructions (on back page) Before  Preparing Form.  Please Print or Type.
Nothing  in this  Form  Shall be  construed  to imply  that the  Commission  has

If the notification  relates to a portion of the filing checked above,  identify
the Item(s) to which the notification relates:


PART I -- REGISTRANT INFORMATION

PART II -- RULES 12b-25(b) AND (c)

If the subject report could not be filed without  unreasonable effort or expense
and the registrant seeks relief pursuant to Rule 12b-25, the following should be
completed. (Check box if appropriate)



              (a) The reasons  described in reasonable  detail in Part III
              of this form could not be  eliminated  without  unreasonable
              effort or expense;

  X           (b) The subject annual report or semi-annual  report/portion
------        thereof  will be filed on or before the  fifteenth  calendar
              day  following  the  prescribed  due  date  or  the  subject

PART III -- NARRATIVE

State below in reasonable detail the reasons why the Form 10-K, 11-K, 20-F, 10-Q
or N-SAR or  portion  thereof,  could not be filed  within the  prescribed  time
period.

The combination of Tenet Information Services,  Inc. and Let's Go Aero, Inc. was
effective June 30, 2004. The  complexities of integrating  the company  required
more time and could not be done without unreasonable effort or expense.

PART IV -- OTHER INFORMATION

(1)  Name  and  telephone  number  of  persons  to  contact  in  regard  to this
     notification

             Marty Williams               (719)                      630-3800
         ---------------------          ----------        ------------------
         (Name)                        (Area Code)        (Telephone Number)


(2)  Have all other periodic  reports  required under Section 13 or 15(d) of the
     Securities Exchange Act of 1934 or Section 30 of the Investment Company Act
     of 1940 during the preceding 12 months (or for such shorter period that the
     registrant was required to file such reports) been filed?  If answer is no,
     identify report(s).    X yes       no
                           ---       ---
Is it anticipated that any significant  change in results of operations from the
corresponding  period for the last fiscal year will be reflected by the earnings
statements to be included in the subject report or portion thereof?  X yes    no
                                                                    ---    ---
If so, attach an explanation of the  anticipated  change,  both  narratively and
quantitatively, and, if appropriate, state the reasons why a reasonable estimate
of the results cannot be made.

The results of operations are for Let's Go Aero, Inc. and not Tenet  Information
Services,  Inc.  due  to the  acquisition  of  Let's  Go  Aero,  Inc.  by  Tenet
Information  Services,  Inc. For accounting  purposes,  the accounting will be a
continuation of Let's Go Aero's businesses rather than that of Tenet Information
Service's.
