I've bike-camped in Coe Park many times now, and I often stop right here for some relief from the sun and consume an energy bar (a Clif bar, usually) and more water.
Much of this road becomes quite narrow after passing Anderson Reservoir and has no shoulder where stopping for a break would be practical.
Also, there's almost no traffic up here beyond Anderson Reservoir, (a popular destination for noisy day-trippers) so the feeling of arriving in the wilderness is starting to set in, even though I'm not there yet.
Once my break is over and I return to my slow uphill pedaling, the driver of a car on its way down the hill (probably from Coe Park) gives me a thumbs-up as he passes me. Cool!
