Am wondering if safety concerns aren't more for motorists than runners & cyclists? Having lived near DV for several years, and often traveling thru it, I found there are frequent "events" which don't receive much publicity. Sections of the hundreds of miles of highway in the part have steep dropoffs in places, sometimes without guardrails, so suddenly coming upon runners & cyclists without advance warning can be discerting to say the least. When these encounters happen on a corner, forcing one driver into the other lane ... I've been in one of near misses more than once.

The above is pure conjecture on my part. But I have a hunch there are myriad complaints from the motoring public re: the risks these events place on everyone.
