TG-
Yes, you have to register. They have you fill out a couple of forms- YIPES- get on the scale- and then they give you the all important sparkly wristband. They also go over your packet and stickers. If you are getting in Thursday night you'll be fine. I actually plan to voly for your race. I want to be a catcher at the midnight hour, but I'll prolly wear MANY hats that day.
