BIF Workshops/Seminars in mid-Atlantic area?

I'm looking to attend a BIF workshop or seminar in the mid-Atlantic region. Although I'm in PA, I'd be willing to travel 2-3 hrs to go to one where I could learn some tips and techniques to refine my skills and also identify potential BIF locations. My preference is shooting raptors: eagles, hawks and osprey. Although I've been a photographer for close to 40 years, I've only been doing BIF for the past 3 and feel that I need some guidance to achieve my full potential.

Any and all suggestions would be greatly appreciated!

As far as locations are concerned I think Conowingo is as good as it gets right now. During raptor migration Hawk Mountain is good but the birds don't always get close.
