Camping is sort of an honor system thing. Everyone has to leave valuables laying around camp sites. Tent campers especialy. Coolers,tents,chairs,laterns,sleeping bags etc. So everyone takes a risk. I wouldnt put to much thought into it,if you do it will just leave you paranoid when out at the beach or hiking etc. Everytime we leave our tent,our tent heaters,flashlights,food everything has to stay left alone. My jeep has no door on during the summer and it is vulnerable, it has tools,cb radio,jacks,chains,straps,all sorts of odds and ends but somtimes it has to get left that way with all my stuff inside sitting in plain view. Its just a risk we campers takes. I am not saying be blind, but you got to get out and relax.
