I'd probably knock door to door where ever you live until I found a pair. If you don't wear some type of water proof pants you are going to be miserable. Your friends friends don't have even one spare pair of pants you could borrow? Whatever you do don't wear jeans. And yes I'd agree that your next best bet would be some rain gear and some thick layering.
on average i see atleast 15-20 of those jean wearing skiing fools
must be those migrants from further south and west
