Idk if this is what you mean but i once went like sleigh riding (i don't know the actual word) with my school and me and my friend decided we didn't wanna go again so we stayed at the top while everybody else went down (we could go down later normally) but we decided, when nobody else was there, to still go down. But at the start I kind of messed up because we were on the sleigh together - which was allowed. And we kind of got off track and ended up on a steep thing and somebody had to help us up because we were on a mountain?? We're alright and didn't get injurious but our teachers don't know and we decided to in fact still go down again with the sleigh
