Historically my friend and I have driven from my ex winter home in CA to my summer home in NC. There's so much room between A and B that we could "make our own adventure" pretty easily. This winter buzzgirl and I lived in southern Vermont instead of California. My friend and I still want to make a trip out of it, but we can't come up with anything, especially around the 1st week of April, that we really want to do or visit. In the past we've visited theme parks, Detroit, car museums, Biosphere 2, the 10th Tallest Pyramid and countless other attractions big and small.
We're pouring over maps and checking out Atlas Obscura for everything vaguely between VT and NC. We want to do Cedar Point, but alas they don't open until May. Would love if anybody knows of a cool thing, place, event on the east coast roughly April 1-6.
