I hope you have a lot of power... The road over Hogback Mt. is brutal, lot of switchbacks (curves before a steep grade). No way to get a run before the grade, you just have to power up it. But then, it's a major east/west road and the trucks traverse it everyday.
If you a little underpowered with your rig, it will be a struggle. I just blast right up it, but then have to wait on the top for my traveling companions (I won't say the brand of his truck...)
Let us know what you think about Greenwood Lodge and Campsites... Write up sounds good, I may want to go there sometime.
