Much more complicated than PA hunting. As far as the upper potomac goes...
-MD owns the river, if you aren't a MD resident, you have to have one with you in the boat to hunt the river. Thats an actual law, not an unsaid rule like the susky. (Ive seen what the local boys up there do to out of state trucks at the ramp for coming around their turf)
-There is no hunting from the MD shore line, thats a Federal no-no. Have to be out in the water. MD side is owned by park service and you arent allowed to hunt from it. VA/WV side is private and to hunt from that side you have to have a VA/WV license and permission from the landowner. Oh yea, and if youre going to be shooting from the WV/VA side at birds on the river, make sure you have a MD resident with you.
-There are various places on the upper potomac that are licensed. In MD, that basically means its Posted in PA terms with a 250yd safety zone from the edge of the licensed area. Many stretches on the river that have islands that are riparian licensed and its less than 250 yds to the shoreline, rendering that stretch of river off limits to hunting. http://www.dnr.state.md.us/wildlife/Lic ... parian.asp
-From November 15-I think its May15 you must wear your life jacket on the river at all times on a boat, not just while under way.
-Water gets dangerous in the winter time, but it can be fun
hope all that helps at least with a what not to do approach.
does having multiple screen names on a forum and having a conversation with yourself make you an extra special rock star hunter?
