I haven't been to Dumont in over 15 years, but we're going next Monday, 4/22. There will be three trucks, one pulling a travel trailer, one pulling an atv trailer, and one truck by itself. I haven't been since they started charging to get in. I searched and found this post saying passes are available at the entrance. So, my question is, do I need to bring cash? Also, what is the fee per truck? $30? Thanks.
