congrats! I just checked to see how far you are from Tucson (I'm going to be at the Tucson ride next month) and you are TOO FAR.

Bathrooms
Bike parking
bike gifts (like jewelry)
and i agree about a bike or two for the smaller people.

one bike shop we have around here sells used bikes. They sell like hotcakes and people come by just to see if there's a cool used bike in stock.

ah.. and you probably already know this; don't sneer at the bikes that come in if they are disgusting walmart bikes.
