Bluegrass is truly a delight; it's acessible to nearly any musical fancy because of it's jubilation and hearty folk mixture. This Saturday Aug. 22, come out to Lake Altoona County Park (directions) for a good ol' fashion romp and stomp featuring nine bands and a fiddle contest – It's the WHYS Bluegrass Festival (a fundraiser for WHYS radio). We've already been heralding the event for sometime, but in case you missed it, here's another notification. Read more about the festival in the extended article or calendar entry.
