My thesis work is mapping and determining properties of craters on Mars. I applied to a Meteor Crater Field Camp for mid-October and was just notified today that I was selected. Now, I've been there before, and last time I walked around the entire rim and took lots of panoramae. And it may be one of the stops I take my parents on just 3 weeks earlier when I'm there for a conference and they're flying in afterwards to go sight-seeing in the Flagstaff area. This being a field camp for a week means I'll be camping there (for a week) and will need to bring all my camping gear on the airplane along with clothes, a pillow, boots, etc. All of my camera gear together goes in a fairly large backpack, plus tripod. So I'm trying to figure this out: a) I've been there before, so I have photos of the crater. Camera stuff would weigh a lot and take up a lot of room and I'm already out of shape to the point that I don't want to be hiking all that stuff plus water everywhere. So do I not bring any camera? b) Been there, done that, but this field camp will likely offer me opportunities to go in/around the crater that people normally don't get to do, such as possibly hike into the crater (very difficult these days to get permission to do that these days). Investing in a small P&S for events like that would be good and light-weight, even though it wouldn't afford me the opportunities of a SLR. c) Suck it up and go all out and bring all the gear for those times during the camp when I'd be hitting myself for not bringing it. I dunno 'bout this one ... what do y'all think?
