The other day I noticed that I was missing a lot of caps from the valve stems on different tires. Lawn tractor, wheelbarrows, rototiller etc. So, I purchased a package to replace the missing ones. Yesterday, while searching for something else in the garage, I pulled out a drawer and lo and behold! there was about thirty of them staring back at me. This happens to me all to often. That's why I have so much stuff laying around.
