Sorry for the wait between S and N.
Welcome to the fourth (but not final...hint hint...) cache of the extreme points of Homewood series. I think I will start a similar series for Vestavia, but not until this one is complete.
Everything to the SW of the junction of Valley and 21st Street is Homewood, so technically, this cache isn't actually in Homewood. Pity.
You are looking for a lock-'n'-lock. Happy hunting! BYOP.
