My camping gear, one can never be to careful, can I? What do you think of it?

I would get rid of about half of that stuff and add others to it. Besides the food and water (already mentioned) I would add toilet paper, soap, tooth brush, tooth paste, deodorant (give the animals a break). Get rid of most of your fire making equipment. One box of matches and a small butane lighter should be fine. If you worry about starting a fire, get fire starter tablets at the army/navy store. these are much smaller than all of that equipment. Get rid of the illumination sticks and get an LED flashlight that can be used for several hundred hours on one set of batteries. Bring an extra set. Depending on where you live, bring rain gear. An emergency poncho is very small. Some kind of small tent with ground floor to keep you dry would be good. A small camper trowel to dig with (unless you are going to lug a toilet into the woods you need to bury your ....).
