My last few trips, I've been all about the travel blog leading up to and during my trips. I'll be doing that with gusto on my roadtrip across the States, but I've also been looking at maybe documenting the trip through photos, specifically time lapsed photos, taking a picture at regular intervals through my roadtrip. As long as the camera is pointing the right way the whole time, I think a little 3 minute video say would be an awesome reminder (http://www.youtube.com/watch?v=3A-unBigvoY)
Anyone done this on their longer road trips, any tips on equipment, set up, etc. I'll be getting a rental, so I won't be able to make any permanent changes to the vehicle.
