3N34 from Crab Flats to the Deep Creek crossing is about 3 miles and yeah, that's the fun part of the Dishpan Springs trail.
But, here http://www.fs.fed.us/r5/sanbernardino/conditions/ it says "Forest Road Closures:
3N34 From 2N26Y to Tent Peg Campground (Dishpan Springs) remains closed until further notice due to bridge damage."
Going the other way to the crossing from Lake Arrowhead (along Hook Creek Rd) is ...booorrrring
The other side of 3N34 to Devils Hole was open a few weeks ago, but that's pretty boring too unless you just wanna go swimming after a hot day on John Bull and Holcomb.
