Can we do water balloons in the field if we make sure everything is cleaned up after?

Sounds like fun! Maybe offer prizes for those who pick up the most baloon pieces.

Agreed, nothing says you can't Nd if you cleaned up afterwards I dont see the harm in it.

I'd imagine it would be fine if cleaned up.

Ditto.

Clean up your mess after your done

There are no signs posted saying you can't!

I dont see why not
