Can you use trees to put up a hammock?

I don't see any reason why not. If its not allowed I'm sure someone will let you know. Otherwise enjoy!

Yes

As longest you tie it up it's fine.

I've never seen one in use yet.

And it's not on any rules on the website I'm sure a hammock would be fine, just don't damage the trees

Unless the trees are 50 yards apart unless you have long hammock there are lots of people today at streamer train and tomorrow 12-2:30 to hop in.

This would probably not be allowed
