I believe you can book online, if your don't want to make the trip up and be disappointed. I live near the space and it is hit or miss on weekend. If you can come during the week there is usually space. If you book at the location and no one is at the station you will have to pay cash. The trout at the pond are lively the past couple vod days if that peaked your interest.
You'd probably have to try and call to find out. ^-^/
