Abstract: A portable halfpipe and method for quickly constructing the same is disclosed. The portable halfpipe includes a left arcuate module, a right arcuate module, and preferably, an intermediate planar module therebetween. Quick release connectors are used between the modules to allow the modules to be quickly connected and disconnected. Ideally, the quick release connector is a rotolock which includes a male portion having a rotatably mounted hook therein and a receiving post mounted in a cooperating female portion. The male and female portions are affixed in modules to be joined together. The engagement of the hook with the receiving post causes the modules to abut and clamp together. The method includes abutting modules together and rotating hooks to grasp receiving members thereby clamping the modules together.
