That goes twice for me.I'd gladly pay to play...
The last time I went to Kahuku dirt bike track it was free (prolly because I was in my truck w/o a bike), but I remember paying $3.00 a while ago.
$3.00, shoot even $5.00...still cheaper than a movie. If the money goes toward access, maintenance, and management I'm all for it.
If a park became available for us to use, I'd gladly pay a small fee to use it, rather than take my chances and get thrown out of some other area by the man.
