To Those Who Think It's Boring
It's only as fun as you make it and you don't have to do all the challenges to complete it. There are so many twist and crazy characters I don't see how you can get bored. My main tip though is that you can get an improved campsite, set it up, and travel to a way point anywhere you're allowed to go in about 2-5 mins. It cuts down a lot on riding time, although I like to ride around most of the time, because you never know what you'll run into and I can get some hunting done to make money.
