Also from the shore
I'm also from the Eastern Shore, and it depends where on the shore you are. I'm in Cambridge, and it is much easier (quicker) for me to cross the Bay Bridge and head up via 95. If you are farther north it may be better for you to go up 301, but you will still have to double back around to the West either way. If you decide to take 95, I think Havre deGrace is the last exit before 95 becomes a toll road.
Also since you're so close, if you don't find what you're looking for at the show, let me know...I have a few animals I may be willing to part with at the moment.
