When you're looking inspiration for your next vacation, Popular Science probably doesn't come to mind, but the May 2011 issue is chock full of ideas. Their "Mind trips article" (not online yet) has some great ideas for, uh, geekcations.
If theme parks don't float your boat and trees aren't your friends, you might like:
Digging for dinos
Witnessing a car crash
Learning about robots* or
visiting a lab- they suggested Brookhaven, but I'm understandably partial to Argonne.
If you're looking for other unique getaway opportunities, check our Jennifer Miner's post on volunteer vacations over at The Vacation Gals.
Do you have a suggestion for a unique vacation?
* We hope to make a stop in the 'Burgh this summer.
