Brief version that I heard from ex Swinley BIke Hub employee goes along the lines of features built without any real consideration for the main riding population of Swinley and even these not finished / have issues that need addressing. Currently do not have the money / time /resource to rethink and rebuild. Don’t expect it to open at any time soon.
Personally, given the majority of Swinley riders (myself included for for the big line at the moment I expect) would never get anywhere near them, I think they were pretty stupid to build it in the first place. A progressive skills area with tables, drops etc would have been much better use of space than large drops, doubles and step downs.
