Welcome to the forum! About the ramps and skiing... what part of the bay area do you live in?

Unfortunately, most of the ramps around here are going to have a lot of traffic so it may not be right around the ramp that will be best suited. I know in our area, Pinellas Point, if you put in at the Bay Vista ramp and head toward the Meisner Bridge, just before you get there there are markers leading to Holiday Inn Sunspree.

If you follow those back a bit there's a nice area that's suited well for skiing.
