Paintball

Paintball has enjoyed a certain level of popularity in the greater Sacramento area throughout its history as a game/sport. Airsoft and Nerf are similar activities. Paintball is a surprisingly fun activity for the weekend. Get a group of friends together and head on out. It can be quite pricey however.

• Davis Paintball Center - all day rental package is $25, or only $10 if you have your own equipment. AllisonEriksen recommends beginners not try to play there on Sundays, as that is when the professional teams go to practice, and they generally don't want to let inexperienced players into the games.

• Big 5 Sporting Goods has a limited selection of markers (paintball guns) and facemasks. Also their paintballs are quite a bit cheaper that what Davis Paintball Center charges on the field.
  

• Apparently ACE Hardware carries some paintball supplies... somewhere. I only know this from an ad in the Aggie advertising a sale on paintball equipment.

• UC Davis has an active paintball sports club team (at least for 2007-2008). You can contact them through this forum
