any nj, pa, ny riders out there?

I just saw a video on TikTok where some guy took the rear end off an ATV and bolted on a roto tiller in place of rear wheels. I wish i saved that video to post here....good thing it was 4 wheel drive...lol but, it seemed to work.
I'm not sure how he made it bolt on to the drive....

The family has two quads and have been asking where to ride around here- we are about 70 miles north of spokane and looking for places that are nice to go visit for beginners.
We have a 2003 Polaris sportsman, and a 2004 Artic Cat 2-up (I forget the size)
 

I am new to the area and looking for some areas to ride and explore by atv. Does anyone recomend any trails?

I just got my first Atv and I’m looking for some fun places to ride it in northern Ohio. 

I just got a 2007 Honda trx400ex and I'm looking for places to ride. Is there any website that gives a list of areas where atvs are allowed?
