I've known a couple groups to run it. They had access via another friend who's good buddies with the owner of the apple orchard property accessing it from the Rockville side. Sounded like it was decent boating, but lots of access issues.
For other info on stuff in the area my dad operates a basic website with some run info. The contact on there will get you him and he'll have the most up to date stuff on the EF, or access issues on the N. fork.
