The closest trail for us is Kaner 676 which is just off the 1903 on the map. Their proposed location is only a minute or two from Long Meadow so distance to any of the trails is unaffected. The rest of the trails we use are mostly accessed off Hwy410 or via other trails. The only way we're getting closer to the trails is if we move to a dispersed site up off of the 1708 Milk Creek road up to the rocks, which I don't believe would be a good move for an event like this.
Long Meadow has easy accessibility for trucks/trailers, bathrooms, no Forest Pass requirements, and usually plenty of spaces (if their isn't a dirt bike poker run going on). It's going to be tough to find a replacement.
