I have to say that the best field i have been to besides HellSurvivors (Monster Game) is Bull Creek. I know for a FACT that none of you have heard of it or even know where it is. I like the "africa" part of it best.
The field where the D-DAY game in Oklahoma is kick ass, that game rocks too. Alot of work put into those fields. The next game will be June 7th, 8th and 9th of 2002. the website is bunkerextreme.com Check it out.
