Yes actually and I’m glad you asked.
I hope to offer rentals on a frozen lake at a location near Minneapolis where I live… Initially hoped to started taking bookings on Jan 3rd, but I think I’ll have to push that out.
Here’s the logo thing.
Brand story (Designer is going to have to swap out that pic…)
Been working on finding a location, fleet of karts, insurance, marketing plan etc etc.
Location is the biggest challenge. Finding lakes is easy, but figuring out who controls the access has been hard. Sure, I can easily just turn up with my own kart and rip around practically any lake. But obviusly operating a karting business on there without permits of some sort is just asking to be shut down…
Of course, with evaluating lakes comes track layout ideas…
Here’s Lonato squeezed onto a lake about 8 mins from my house…
The frozen lake pictured above from last year is still an option, but it’s 1hr north of where I live.
That said, interlagos in it’s entirety fits on there haha
That’s one REALLY cool thing about this you can prettymuch build whatever you want. The frozen field of dreams for kart racers 
The biggest challenge is trying to figure this out and run it on a limited schedule as a side project. Right now I think I’m looking at running every other week on Fri, Sat, Sun. Between that and limited daylight hours, it’s hard to make the numbers work when I really only have until march before the lakes get a bit sketch.
