my #1 reason is simple, the people. ive met my best friends thru this wonderfull sport. friendships that i kno will last a very long time. but dont get me wrong, being able to throw a piece of plastic 450-500 ft is frickin awesome too. :)
Like the first comment on this topic. Watching those discs take flight and letting it glide on down the fairway. The social aspect is another great reason. You never know who you're going to run in to.
