10 am is when they plan to begin things at Colemans. If you wish to be there at the start, you'll need to leave at 9:xx or whatever to arrive at 10.
The final meet location is Colemans PS Woodbridge. My point of thso thread was to get the folks who live close to eachother to orgranize at ride down in groups. If you want to start a meet up & ride down thread for your hood - go for it.
As far as leaving you bike, you might wish to talk to them about that, Bret/Desmo996 can probably help you on that account. This is a special event on a Sunday and the store will NOT be open for regular business. So it's quite possible that you won't be able to drop off your bike that day. But Brett, Lucy(Cookie) and Ben(Coolasice) have been pretty d**n good to us so far, so there is a chance.
