My tool bag is actually a tool box. I changed it over last year after I accumulated a few more necessities. Little bugger is getting heavy now but it's not overloaded with everything, just good necessary tools. I'll take a picture sometime today or tomorrow and post it.
Stacie, you will appreciate having that toolkit around. Put a handfull of zip ties in it. They are great for tieing up hoses, power cords, lights, etc. Keep a roll of duct tape, pipe tape and electrical tape in there too. Electrical tape is great for sinching things together and doesn't make a sticky mess like some duct tapes can. Also keep a bag of bungee cords in different sizes (not in the tool box though) and small/medium clips. I buy small clips at Home Depot (usually right at the checkout counter). They are great for hanging lights on your canopy or pop up shelter. My camping buddies love that I come prepared and on many occasions I've heard, "well, if you don't have it, Becca will". Yep, probably do.
