Surfrat, I'm not sure about your area, but here in RI I hunt the schoolyards all the time and have never been bothered. I go on weekends, early in the morning. I usually head out if kids come along to use the playground cuz I don't want Moms getting worried about some wierdo with a detector hunting around where their kids are playing. Sometimes I bring my own kids if the weather is nice, and they can get some fresh air running around the playground while I hunt and scoop up trash. If your not sure, ask someone, even if it's just a call to the school administration for your town. As long as it's off hours, and you fill your holes properly and haul out trash, they shouldn't have a problem with it. After all, your taxes pay for the school, teachers salaries and the gym equipmenty, right? Good luck!
