Non-Gaming, but just as Geeky.

Another hobby that I partake in is Airsoft. For those who don't know what this is, it's where grown men (and a few women) run around woods, fields and other obstacles with b.b. guns shooting each other for fun. Yes, it can be painful, especially if you get shot in the face, but it's is as safe as any other outdoor activity. Face masks, or goggles are mandatory to protect the eyes. The reason I like this way more than paint-balling is that I can use replicas of real guns, rather than ugly bulbous tubes. It is an expensive hobby to start, with guns starting at £150 and going way, way higher. However once you have your kit, the ammo itself is very cheap. £8 getting you around 5000 b.b.s.
