When was the last time you went out there? They redid the track a few months ago. They made it big bike friendly. I haven't ridden it but I've been there and do go past it often and it does look worthy of a visit.
I went two there about two months ago (Thanksgiving), the track was the same since July when I joined. The layout is fun, just that I got bored after riding it 5 or 6 times, and no changes to the track or any maintenance to it.
The guy at the gate (Jhony) is pretty cool and will let you ride as long as he thinks you are interested in buying a vintage bike.
