Look for the deposit box by the notice board. There should be pay slips with instructions you can fill out.
On the right side, after you enter, is a covered billboard with pricing & local information. Near that is a lockbox with envelopes that you write the site number & # of days you'll be there. Once you find a site, you fill it out & place your payment in it, remove the stub for your site stanchion, and hang tag for your mirror, then I think you have 30 minutes, or so, to submit your payment to the lockbox.
