Back to the subject a bit....
Just got a call from the Mild 2 Wild guys... (Gas Gas/MZ dealers formerly on the Rock Road...) and they're the ones runnig this deal. They moved out to Troy a while agoand apparently business is great.
They're the ones running this Proving Grounds deal. They're saying they'll have a website up in the next week or two.
As far as the 'membership' thing, it's $200 per person for one year and $500 for a family of five for one year. That gives access to the entire 'complex'. Otherwise, it's $15 per day, per person.
I was told this time that directions were not being given out because they don't want a bunch of people out snooping around while they're trying to get the work finished. I guess they guy I talked to on Saturday didn't get that bit of info...
The Mild 2 Wild shop is currently located in Troy, just off of Lincoln Dr. (61 N to 47, W on 47, first light is Lincoln, turn right and they're on the left.
FWIW, they claim to have Matt and Nick helping them with the SM track layout.
