Thanks for the vicarious trip - especially the pix of you and the baby. Good on you for insuring that at least some children still know what is on the other side of the walls. Thanks!

When erecting a tarp in this kind of situation, I find the easiest way is to use two ropes, one at the high end and one at the low end. make sure there is an reasonable amount of slope to keep the water off. Tie one end to tree then make a small loop where you want a corner of the tarp. Slip the loop through the grommet and place a small stick or other object through the loop and pull snug. Do this with all the grommets and tie off to the other tree with a sliding knot. This allows you to move the tarp if necessary. The trees don't need to be in a straight line with the position of the tarp. Not my idea, I was shown it YEARS ago by one of my mentors. Been using it for all those years any time I put up a tarp and there are trees. Saves LOTS of work trying to set up some type of poles.

Respectfully,
