re: get that 12V adapter
JMS, my first post got a bit more serious than I intented. I'd lOVE to just sit up there waiting for something to happen, but I doubt they have wi-fi in the parking lot. Not to mention the difficulty of convincing my girlfriend to spend her whole trip that way. She actually does think that watching a mountain blow up would be cool and has humored my previous forrays to go look at holes in the ground or barren lava flows, but this would be a bit much.
Mostly, though, it's supposed to be cloudy and rainy by the time I get there so there's not likely to be anything to see...
