One of our actors discovers the joys of dolly surfing!
Each track is in three sections connected only by short pieces (4 in) of the same PVC with a slot cut in it. It's laid over slightly uneven ground and anchored only at the ends with a couple of spikes (which also keep the dolly from running off the ends).
Even with all the inherent wobbliness, it works flawlessly!
Thanks to all the people in the DIY forum for terrific designs and improvements to this system!
