Pros:
You can play Bull Run in about a hour. You have a decent chance of hitting birdies which is good for people who do not play disc golf very often and newbies. It is a great course to start learning the game. My mid range game has improved because of Bull Run. I often Roc the entire course.
You can play the course like three - four times and make a afternoon of fun. You will not birdie as much as you think and when you do hit a ace the thrill is just as great.
I love this course. Don't listen to all the naysayer's. Bull Run is a small course but fun.
Other Thoughts:
Bull Run is a great course to play if you don't have alot of time but want to get exercise and practice your skills. There are a ton of trees and you really have to aim well to birdie most holes.
