I think it's all about making up your mind to put your "toys" away. I use electric tools and I am constantly having to roll up long electrical cords so that I don't leave them out in the weather, or where "Buster Brown" will chew on them plugged in. It is SUCH an effort to do so. Certainly my DD's don't always put their toys away, but we drive by a place with not one but TWO John Deere riding mowers that have been left out to rust for nearly two years now. Obviously they don't run, but what a waste when they could have been put away. The owners have a building available. At the very least a tarp would have helped. Even my wheelbarrows are under shelter, if not in a building when I am not using them, which is easily 6.5 days/week--there are days that I work and cannot clean up with them.
DH and I have been straightening up our toolshed, left a mess by our DD's from the last project they did there, though they use their own garage now. He even found some very expensive bullets, rim shot, for a gun that he owns and he even glued the old box back together. I am moving ALL tools to my free standing 7 drawer toolbox there, however, when I need to buy at Harbor Freight I will pick up a freebie, like the 4 in 1 screwdriver that I now keep in this desk under my laptop in my home office. Just used it today, and Yes, I put it back in the drawer.
It is great to go do a job and know that your tools will be available, instead of spending 1/2 the day looking for them and giving up on the job.
