                  Responses to the Securities and Exchange Commission
                  Staff Comments dated May 16, 2006 Regarding
                  Amendment No. 2 to the Registration Statement on Form SB-2
                  Filed on May 8, 2006

Dear Mr. Owings:

     This letter responds to the staff's comments set forth in the May 16, 2006
letter regarding the above-referenced Amendment No. 2 to Form SB-2 registration
statement. For your convenience, the staff's comments are included below and we
have numbered our responses accordingly.

     In connection with our response to the staff's comments, we hereby
acknowledge that:

     o    the  Company is  responsible  for the  adequacy  and  accuracy  of the
          disclosure in the filing;

     o    staff comments or changes to disclosure in response to staff comments
          do not foreclose the SEC from taking any action with respect to the
          filing; and

     o    the Company may not assert staff comments as a defense in any
          proceeding initiated by the SEC or any person under the federal
          securities laws of the United States.

Our responses are as follows:

Staff Comment No. 1:

     We note your response to our prior comment 9; however,  based on our review
     of your  detailed  breakout of other  income/expenses,  it appears that you
     have improperly  classified impairment losses on assets as well as the loss
     on the disposal of your assets as other  expenses/losses  instead of within
     operating  expenses.  Given the relative  significance  of these charges to
     operating income,  please revise your financial statements to reclass these
     costs from  other  expenses/losses  to  operating  expenses.  Additionally,
     disclosure  regarding the  impairment of these assets should be made in the
     notes to the financial statements. For further guidance refer to paragraphs
     25 through 26 as well as paragraph 45 of SFAS 144.

The Company's Response:

     The Company has determined  that the impairment  loss of $134,630 should be
     reclassified as a loss on disposal of assets,  as the assets were taken out
     of service as of December 31, 2005.  Considering this  reclassification and
     the  original  loss  on  disposal  of  assets  of  $93,384,  the  financial
     statements have been revised to comply with SFAS 144.

Staff Comment No. 2:

     The financial  statements should be updated,  as necessary,  to comply with
     Item 310(g) of Regulation S-B.

The Company's Response:

     The company has revised its  registration  statement to include the interim
     financial  statements  for the period ended March 31, 2006,  to comply with
     Item  310(g) of  Regulation  S-B.  The  Company  has also made  appropriate
     revisions to the disclosure to accommodate  the inclusion of such financial
     statements.

Staff Comment No. 3:

     Please provide a currently dated signed consent from the independent public
     accountant in the amendment.


The Company's Response:

     The  company  has  included  a  currently  dated  signed  consent  from the
     independent public accountant as requested.
