Any of you ever hunt large Rivers like the Mississippi or Ohio? I just got back from vacation at the beach and had a ball in the surf with my Excal. Most of the lakes around here that have beaches are owned by the State or USFWS, some by the USACE (may let you hunt, haven't checked yet). Anyhow there is a bunch of river miles with sandbars that have a lot of pleasure boaters/swimmers nearby. Anyhow, just checking to see how many of you have had success with it. I know lots of folks that walk the banks for Native American artifacts so I imagine there should be some metal too. Thanks.
