i'm sorry man, but the flat down box is the only remotely good feature in the boler park. I stop in there sometimes when I'm visiting people in london, and it just needs a lot of work
I talked to the guy who runs the park there too, and if he bought an airbag instead of investing in new rails it really just confirms what an idiot he is. Your rails are like a thousand years old and all slide like they have three inches of rust on them. The park crew is lazy as crap and wastes the only decent jibs you guys have on making stupid ass features (ie close out rail, ultra steep down rail, rainbow box to flat). I rode a jump there once and it literally had two lips on one takeoff, i didn't know that was possible
IMO if they moved the park to the new hill, revamped the park crew to people who actually care enough to think, and invested in two or three new rails, you guys could have a moderately decent terrain park. It's better than nothing I know, but it needs a lot of work
