OK, So I am going to Cousin's outdoor in Coram for the first time saturday (tomorrow) morning.
Every field is a little different so I figured I would ask what I should know before before I go.

First off I would like to start playing early, but I dont want to be waiting around for walk on groups to be formed up, what time should I get there?
I live like 2 minutes away, if I forget some thing or want to take an hour off for lunch, can I leave and then re-enter?
I saw in another thread that I could buy a case of paint from their local store and bring it in with a receipt. Anyone do this? Is it worth it? I dont want to get there and have to buy a second case-o-paint.
Any other advice is welcome...
Oh yeah, what about HighVelocity? I dont want to start a big debate but Im open to opinions about the two places. Obviously I havent been to either.
