My friend used one of those once and a car behind him narrowly missed him and went into a tractor full of manure, apparently it was even captured on film. He did say you had to practice real hard to control the hover!!
In France last year the slopes had bumps on them in the afternoon (moguls?) Overnight they took them away so the slopes were nice and smooth in the morning to get used to skiing again. After lunch the staff had put them back onto the hill.
Do they do this in Bansko and if so can I arrange a tour around the mogul storage facility as it must be rather impressive
I always find it hard to stomp on the brake as the skis end-up catching the clutch, the accelerator and the brake at the same time - try using your knuckles - just lift them when you want to go faster!!
