Greetings:

Because one of the major topics scheduled for the July meeting has moved to the Fall (ground water discussion), we

 have decided to cancel the 7/20 meeting.

I have reserved the large 11th floor conference room here in Crystal Mall 2, for Monday 9/27 and Monday 10/4. please

 let me know if there are major conflicts with either of these dates.

We look forward to a productive meeting in the Fall!
