The US Army Corps of Engineers at Mark Twain Lake invite groups or individuals to come to the Visitor Center on Sat. March 16th or Sun. March 17th from 10 to 4 for a spring cleanup. Volunteers will have the chance to assist Park Rangers with mulching, pruning, dead-heading, leaf removal and assist in overall sprucing and helping to get ready for another busy recreation season. This is a great opportunity for anyone looking to fulfill hours needed for civic involvement, community service or for the individual simply looking to improve the esthetics of a popular local attraction.
