text: It's about a half-hour from Gilbert and not free, but almost. Lost Dutchman State Park, right in front of the Superstition Mountains, is $25 (I think) and available as long as it's not being used. Dunno about tomorrow, but should be good for a fairly short notice as long as you don't hit it Veteran's Day. Throw in a parking fee and you're good to go. 6109 N. Apache Trail; (480) 982-4485.\n\nWe were thinking of using it but ended up having too many guests -- sounds like you might just have a small group/couple of people.
