Take a guided hike in the Casper area to look for seasonal, edible plants. Learn about foraging rules and how to identify, gather, and use native edible plants. You must be able to walk at least three miles on varied terrain and at higher elevations. There may be limited access to restrooms or outhouses. Wear comfortable walking shoes, sunscreen, a hat, work gloves, and dress in layers. Bring a sack lunch, trowel, and small pruning shears. Mon., Apr. 13, is the last day to receive a fee refund.
