I had my first tandem there in 2004. Do to the overwhelming sense of support and belonging I went back did AFF, got my A and B license there. I have sense moved away. There are numerous closer DZ's that I've jumped around my house. It's well worth the 6 hour drive to get there.
If you want to learn something, GO HERE! If you need a place to stay at night, GO HERE!It's free, you'll hang out with hilarous folks, and wake up with the beautiful smell of a dz.
It's just a home for skydivers!
Also, the prices are very fair. They don't cheat you out of altitude.
I've jumped at ASC's sister DZ in Pell City, AL and they were nice folks but overpriced for the altitude. Also, the safety measures at Cullman are little more by the book.
