Annual is $30 at the back channel.
There is a pay box with day passes and pencils. The pass is carbon paper and copies what you write onto the envelope. Probably wouldn’t be a bad idea to keep a pen in your truck for the time the pencils disappear.
I’ve already saw several people use the ramp without paying. I don’t know how much they patrol it, but I figure I better pay my 5 bucks and not worry about a parking ticket.
