"B28" is a Beginner/Easy trail in the Ammo Dump area of Sycamore Canyon Wilderness Park. It is named in reference to ordinance that "may or may not have been stored" in the WSA silos during the Cold War.
This is a well-established trail that is a great trail for building progressions for new riders. There are a couple of nice turns/one easy drop/one jump.
B28 is located in an environmentally sensitive area. Please do not cut new lines or create new trails in this sector.
