So, there’s a piece of folk wisdom that suggests the best months for oysters are the ones that have the letter “R” in them. That would put April squarely at the tail end of a solid run of eight good months for oyster eating, which may or may not have anything to do with the timing of the annual Appomattox Oyster & Seafood Festival. The fact is, oysters are quite nice year round and April is as noble a month as any to enjoy their briny goodness. The Festival takes over Clover Hill Village (5747 River Ridge Rd.) from noon until 6 p.m. today. There will be beer, cider, wine, various food vendors, live music, family activities, and, of course, plenty of oysters. Tickets are $15 in advance and $25 at the gate.
