I know...that's why my first post was really my suggestion!
I think the only way you can legitimately understand a spot(s), and everything that goes with it is if you have seen it and walked it. Erie shoreline is a real estate premium and so are the public hunting spots in and around it. Heck, the private leases are hard to get.
Between Google Earth and State Maps you can pretty much isolate a 1/2 dozen areas from the comfort of home and then find time to go look at 'em to see if they work. If you're only 40 minutes away...consider yourself lucky!
I hear ya on the public grounds and elmer fudds. The best way I know to fix that is spend the time finding out-of-the-way areas to hunt even if they are not quite as productive (sometimes they have less birds but you shoot more because of no competition). They exist but take work and time to find...and when you find one - don't tell a soul or you'll find elmer there with his buddies in short order.
Any guy can pull up in the center of the public marsh parking lot - and many do. It takes time (and money) to find good public spots...and know that MANY of those skybusters (guys that are idiots afield) scour internet pages cyberscouting for their next 'new' spot to ruin for you and me.
If you make time you will find what you are after.
