If I didn't already have a kayaking trip planned for this weekend...
Isn't the seagull century like a week or two after or before the wild goose chase? you could just do the century option at the wild goose chase.
It's too early for me to plan that far ahead, but I'm putting this ride on my calendar as a possibility for that weekend:

I've been wanting to check it out for a couple of years now but have not been able to do it.
Personally I prefer to ride in this part of Maryland, rather than the eastern shore.
