Last year Alum aloud the ice surfers ( I guess thats what they would be called) use the campers ramp to park they're wind surfers, I used it to walk out on the ice a couple of times and saw several others use it as well. I spoke to the maintenance man at the office one morning, He said he didn't think anyone would say anything, I would imagine it would be up to the park officer if you would be trespassing or not , I would contact the park office if you are planning on going out there.
