I definitely got into motorcycling because of this hobby.
For me and my wife, riding coasters is pretty much our way of life when on vacation. Aside from the thrill of the ride itself, you get to see the country, and the excitement of collecting new credits never gets old. The problem with this hobby IMHO is that when you leave the parks there are very few ways to satisfy your thrill appetite that replicate the sensations you get on a coaster. My brother and several friends ride bikes, and one of them jokingly said I should take up the hobby because it would be like riding the front row of a coaster on a track that goes on for as long as you desire.
They were right to a pretty good extent: The sensations you get when riding a bike on a good backroad, open highway, etc., are an excellent way to experience some of the thrills you get on a coaster.
