i went skiing at Hillend a few times in 1968 / 1969. one evening session the downramps from the draglifts had been given a generous helping of old-skool, yellow floor polish - which made for a faster-than-average descent. then it started to snow !! holy bejeesus SUI F IN CIDAL. happy days!! good to see the place still running - and loads more runs available.
This type of setup is pretty amazing. Allowing for skiing all season long. I assume this is doable for snowboarding as well. I can't imagine the maintenance on these whatever you call it. The more than average need to inspect them could be tiresome.
