This is another plan I want in my RR to. Now if you have one near or just a drive up the road then (if your in the US) taking photos on public ROW is not a offince. They might send security and or police but be clam and let them know what your doing but everything should be ok. Just don't act like a jerk about it. Info here: http://www.krages.com/bpkphoto.htm
