Q.winterizing barrel cacti
I have three small barrel cacti in pots. I need to winterize them. I live in Prescott, Arizona at about 5,000 ft elevation. Can I leave them outside for the winter, or do I need to move them indoors?

It looks like you are in gardening zone 7, while barrel cacti are only winter-hardy in zones 9 and warmer. Therefore, I recommend bringing your cacti indoors for the winter.
