one of the coolest things ive ever built in the snow would be a really fat snowman, i had always loved building them as a kid, and one year i decided i was going to build the best snowman ever! he was really big and plumb, i even gave him a scarf, hat, mittens buttons arms eyes and a smile with a carrot nose. he last a full 2 days before he was ruined by the wind. if i had all the snow in the world to build something id build myself a snow hut party house! It'd be warm and people could drink lots and lots of coco! itd be a never ending winter wonderland party.
