My annual winter project is to attack the "wheel monster" that lurks in the top of the barn, along with frames I cannot part with and projects that I do not care to deal with. As wheels that come in that seem to be worth keeping, which qualifies as a decent rim or a decent hub, get tossed into the top of the barn. The fall means climbing up and fighting the monster (pull one wheel, 10 fall on your head). Matching pairs are found, zip-tied together, and put back in the barn. Odd ones are put in a pile and I take them apart over the winter (got nearly 10 done yesterday). My rim storage is running short, so I am going to have to clear some them out.
