The Spring of Life Church in Mesa provides a place for paintballers to gather every Saturday. From novice to experienced they offer three different fields and training for the inexperienced.
I ventured into two of the fields - I wore a bright yellow referee jersey and had one of their volunteers shadow me with a round shield (a green sled) to fend off any lost, flying paintballs. I was hit on the head once, the shield was hit twice, I was hit on my jacket once, and the bottom of my legs got splattered on - it was fun. The paint washed out of my hair and my jacket, but my jeans and shoes are still wounded.
