thanks for the replies. i'm aware of the restrictions on open water (Potomac) and have talked a co-worker who is a MD resident into hunting with me - he has a grand total of two hunts under his belt.
when out at the WMA we saw about 300 mallards; however, we were in the wrong blind, and didn't really have a shot at any. i'll be back there friday morning (diifernt blind), and will be heading over to the eastern shore for deer/duck firday afternoon and saturday.
we tried calling, but so far i'm using a "Cabelas Shell Saver Call". it works great, but the birds don't seem to like it.
