I've been looking at 4 season tents, but when I put up an old tarp I had my whole viewpoint has changed. A tarp seems to be much more versatile versus a tent-the configurations are many when setting up a tarp. I'm wondering what you guys use and what recommendations you have for all season camping. A tarp might not be as good as a tent for winter camping, but I'm impressed by their versatility at this point.
