outdoor shooting

Good day brothers, was wondering if any of you can tell me of any places in Martin County where I can take my boys shooting? We used to be able to drive out to the cane fields here in Palm Beach County and go plinking all day long, but that is coming to an end. There are no more woods anywhere thank to our county commissioners and their greedy developer buddies. I used to just go along a canal bank and shoot at bottles and cans in the water, but it's just getting too populated. We aren't doing anything extra big, just .22LR, and only shoot at inanimate objects. It seems like you guys have a lot more open space to the west of your county, can any one point me in a good spot. I'd really appreciate it.

thanks
