Can't say I've been impressed with the few uke offerings at the Denver Folklore Center—hardly worth the trip, unless you want a kitschy, unplayable wall hanging. Instead, contact the Olde Town Pickin' Parlor out in Arvada, check if they have anything it might be worth the venture to see.
The main Denver and Boulder groups just had their monthly meetings, and the Lakewood-based Rocky Mountain Ukulele Orchestra rehearses on Sunday. Bad timing, I'm afraid.
