Yeah I found my way in. Can't believe I didn't see the 4100. Must have thought it was a residential driveway. Thanks for the help. Was way more productive trip this time. Does any one know if they open that gate at the river on the 4100 during the season? I climbed that hill on the 5200. Good looking area but quite the hump. Next visit will be the areas off of the 4200/4250.
