Ditto the granola bars. They work great and also help me balance my blood sugar levels during a run of games. Plus, try some little packs of cracker "sandwiches" with cheese inside.
Oh yeah, BillyMac was wrong. It's not your bank account number and PIN, it's your debit card number and PIN. There's a difference.
BTW - this is the last weekend of rec games for me this season and it's a fairly easy one. Just a single BV game on Friday night and a B7 and a B6 game on Saturday. I'll probably sleep through these. Then we have our annual ref pizza party on Saturday after games. Won't sleep through that, however.
