Theres a huge rail at a church in my town. I think it has 3 or 4 kinks if I remember well or it might not have any kinks in it at all. I never go there but i'll post a picture if I get one. Its pretty gnarly.
Yeah stare at it for like 15 minutes like I did and figure it out. After trying the first C curve and getting the leaning right it wouldnt be tooo tremendous. Dope rail for sure!
