Well, here's how it might make sense to buy in on one - provided they will permit subleasing or short term rentals.
26 teams equals about 5% of the racers who attend Speedweek. Demographically, that's probably about the slice that could afford a facility of this nature.
Most of those teams wouldn't attend the Motorcycle event, so there's the possibility of a short term rental by the owners to bike teams.
About half of the big guns don't attend World of Speed, so if you own one of the spaces, you've got an opportunity to rent it out for another week.
You're a little better than an hour from Miller Motorsports Park. A team wanting to do some prep work away from prying eyes might be a short term tenant, and they do a lot of events at Miller.
As to the bar, that would have to be a seasonal item - I don't see it making sense with the casinos up the street.
Facilities rentals for outside interests - well, as an AV guy trying to break into locked up concessions in a backwater like Milwaukee, I'm pretty certain the hotels have what little of that there is in Wendover well handled. Why would you even try to rent out a business conference room when the hotels would likely include it with a package?
Other than LSR, Golf and Gambling, the only thing Wendover offers of any value is a truck stop and a damned good CARQUEST. Unless you're operating a steam train and need potable water, it's not a destination for anything else.
Mike, please know I'm not slagging your town, and perhaps there are more economic forces involved than I'm aware of.
I think a better bet - at least for racers - would be to buy the truckstop at exit 4, clean it up, buy a Love's or Pilot franchise, and build secure rental/storage/shop facilities there.
On the other hand, I've been accused of not dreaming big enough.
I hope it happens, I hope it works, I hope they make money, and I hope it doesn't fall into a state of mismanaged disrepair similar to the Bonneville Inn after 5 years.
