A weekend in the snow!!

It was 0 zero degrees and the snow was everywhere around me. Some people were skiing, others were sliding down the mountain with theirs sleighs sledges and others were in the cafe drinking hot chocolate. On this day, me I and some friends went to spend the day in a small town called Valdelinares. It wasn't the first time I saw the snow, but this day had something special. (It is not clear here which snow you mean - snow in general or snow in Valdelinares or the snow on that day)

First we went to a restaurant to for hot drinks hot things while looking through the crystals, windows (ventanas?) then we slipped onto a ski trail to throw us enjoy some sledding, but unfortunately the guard caught us. She was very nice and told us where we could continue having fun with ours sleighs sledges/toboggans. (A sleigh is a large thing drawn by horses) When we got there, we started to make a Snowman with ours hands. Suddenly the first snowball through flew over my head and the snowball war fight began. The laughs and the fun were served. There were laughs and fun aplenty. Half an hour later we continued with our sleighs, sledges and me and a friend and I dared to slide take a blue trail. She was very excited with the idea and meanwhile I was saying I said goodbye to ours another friend just in case we had died should die in the attempt... Finally we survived and it was a great experience!!

Maybe it was the snow, maybe the happiness, or just my friends, but it was a wonderful day.

David - commas are not normally needed before the word "and". 

"Our" is already a plural pronoun and doesn't take an "s" when used as you have done. If you were to say, "that sledge is ours", then the "s" is correct but putting it another way, you say "that is our sledge"
