Yes, it's ethonal free at Koski's corner. Thanks for the name, I couldn't remember it. I kept thinking Junction 95, but that's the bar. Koski's also sells trail passes and appears to allow trailer parking. Didn't specifically ask, but there were quite a few there the couple times we came through. Jubilee just west of Ishpeming has ethonal free premium as well. It's off the spur trail going to Jasper Ridge Inn and brewery. If you're not familiar with that spur trail, when you come back out to 8 from the spur, turn right (feels like east) to go west and turn left (feels like west) to go east. Trail 8 at that intersection is curves twice and is confusing if you're not familiar with it. If you go under the bridge and past Meyer Yamaha... you're going east towards Ishpeming/Marquette.
