I live up in a town that hates hockey (Iowa City), and thus the sporting good stores suck for hockey gear. In fact none of them sell regulation goals (and apprantly right handed sticks are asking too much as well). Since none of them sell goals, I was just going to make one with PVC pipe. The only problem is I am unsure on a couple things dimension wise. I know the regulation goal is 6 feet by 4 feet, but I was wondering, is the 6 feet from inner post to inner post, outer post to outer post, or the middle of the post to the middle of the post?
