I have a friend that owns two Rincon that lives 66 miles from you in Zimmerman doesn't get a chance to ride them much but is heavily into Them. Keeps on wanting me to head up there just might do that after my operations. I sent him most of the pieces I designed for the Rincon he loves them. He told me he has some interesting trails marked out maybe I can get you two hooked up. He stays pretty busy with his business. Nice guy.
Welcome to MN, the land of 10,000 lakes about 3 places to go riding! The DNR has a decent website to show you whats out there. OHV & ATV Trail Locations Map: Minnesota DNR
As you can see around the Metro there’s few places nearby. If you’re looking for camping and riding a good place is Spider Lake near Backus or Paul Bunyan State forest in Akeley. I think those would be about a 3-4 hr from Lakeville.
There is a place out west of the cities I want to try, it's not on the DNR map. If you search the DNR site by name, Meeker county ATV park just opened and I and itching to give it a try. Otherwise I really like the Nemadji Forest for riding and camping.
I also have young kids, I just picked up a can am renegade 800 to add to my atv collection. Now I put my wife on the rincon with one kid, and I'm on the renegade with the other. This way I can get my two sons into the sport hoping that they will start requesting to go riding. I just might be able to ride more now.
