Photo by Karen Kefauver. The Aptos Post Office Jumps have been the training grounds for a number of world-class dirt jumpers. This summer 2012, we bid farewell to these beloved jumps as the land they stand on is slated for construction. On a positive note, MBoSC is contributing $16,000 – raised at the 2011 SCMBF – toward a permanent Aptos Bike Park. Help us pay one last big tribute to these historic jumps by spectating, volunteering, or demo’ing a DJ bike!
