However, I do enjoy mountain biking to a degree  :

New bikepacking route to Wisconsin waterfalls selected as best new route, helps put state on the map

A Wisconsin bikepacking route has earned top honors from Bikepacking.co m, a website that publishes routes and information on bikepacking, essentially backpacking with a bike. 

The route, the Wisconsin Waterfalls Loop, was awarded the best new weeklong route by the website. It beat out routes in New Mexico and Switzerland to win the award, which was determined by editors of the website based on originality/intent, quality of documentation, and which route they would like to ride most. 

The 382-mile route loops around northern Wisconsin, passing 28 waterfalls along the way and is estimated to take six to eight days to complete. About 85% of the route is on unpaved roads.

There’s lots of fishing spots. If you fish. Also lots of scenic lakeshore beaches if you enjoy hikes and playing in the lake. In Wisconsin, you can go to a park and be one of the few people there because there’s so many. In ca, good luck finding a secluded spot. Everywhere you go, there will be people crowding around.
