Dang! I'm going to be in Illinois later this month and into August...but I come back to Phoenix on the 4th. There is a demo in Peoria, IL on the 6th.

I already ride a Giant, so I'm not really "demoing", but I'd really like to go.

Yo Giant, demo in AZ please!

There is a Trek demo in Flagstaff, AZ July 20th. I might try and swing that but I'd def prefer a Giant one.
