If you snowmobile out of the Whoop-Um-Up parking lot and want to travel towards Edna Creek Campground via the connecting trail, you have a Forest Service sign that says you can't do it. The sign is about 1/3 of the way to the campground. It states no motorized vehicles, including atv's, motorcycles, and snowmobiles. Last winter it wasn't there and as the trail enters Edna Creek Campground cement posts block the trail entrance from that end. In the area of the cement posts are signs that say not atv's and motorcycles, but nothing about snowmobiles. Getting around the posts isn't a problem. The problem is the Idaho City groomer has used this trail to access the Edna Creek road, that gives you access East towards Jackson Peak and the North Fork of the Boise River. This trail is the only off highway way to get to the Edna Creek road, unless you want to travel hwy. 21 for a short distance. Behind the sign and at the bottom of the hill is a trail that comes in from the south and maybe that trail is for non-motorized use and the sign is just placed **wrong**? I'm going to contact the Forest Service tomorrow to check it out and I will come back with the Forest Service response. Jens - Region 4 Director ISSA
