When I was younger, I was at my friend for like 3 days, sleeping over all the time. Anyway, It snowed insane amounts of snow and his garden was like this /, like 20° downwards, so you could slide down fast and it made fun. Then one day we went out like 7 in the morning, building a huge snowramp, like 20 metres, the entire garden long, like those snow bob tunnels in TV and we slided down the whole day. Was so awesome. Never gonna forget that. :3
