So what, berries have been proven to not exist and only appear in dreams!?!? Lol jk, I know what ya mean. But with season's I think it would be interesting if some routes opened up/closed for seasons. Like a water route being able to walk upon in winter, closed in spring (for all the excess water in case you don't know why it would be), then a peaceful river in Summer and fall. A sidenote, I would like for YOU to be able to swim, at least a little in some places. And I also wonder... if you climbed a snow bank to a cliff during winter, was inactive till "summer," would you be stuck till winter again? Or would there be an alternate way off? Not including fly.
