Food, I carry a 10ft roll of orange surveyors tape in my pack for flagging when needed. Say I decide to go off trail to get a view, I flag from the main trail out to where it drops off. I remove it on the way back, same deal. I like your situation better though <img src="/forums/images/graemlins/cool.gif" alt="" />

That sounds like a fun way to meet other folks coming into an area to camp with <img src="/forums/images/graemlins/smirk.gif" alt="" />
