That's pretty awesome. The space shuttle is at the $15 museum and I'd definitely be down for going, but it is a little bit of a drive from Baltimore (solely because of traffic and not distance).
I'd also like to see Poe's house too, if we have a large enough group. I tried to see it once before, but it was closed and we just ended up seeing the cemetery instead. Be advised, Poe's house is sorta in a not so great neighborhood, so a larger group would be better.
