Obviously, I'm going to have to seal the edges somehow so that no air can get beneath them.
-----------------
We used to have a tarp over our firewood. Two, sometimes three, cords. We were lucky in that cement blocks held the tarps down. Seems like you need one of the following:
1) Cinder Block - they sell cinder blocks without the holes in them. If you lay them edge to edge, without any spaces at all, they should hold your tarp/s down.
Having a little (very little) experience with this method, I would suggest you SINK an inch or two of the cinder blocks, as a strong wind will move them;

2) 720 feet of edge: 720 feet, divided by 12 inches equals 60 cement blocks. Sometimes you can get cement blocks for $1.00 each, but not likely. You have to decide if this is the route you want to go.
DIRT FROM THE FOREST? You don't think this dirt is going to blow away? I do. They also sell dense cinder blocks, so no air can enter the tarp/s;
3) REBAR: did you think about rebar? Again, edge to edge, but it has to be thick enough to bury part of it.

The advantage of this, imo, is that you can roll it a couple of inches in the Spring, and back on the tarp in the Fall. I forget what the tarps are for, dammit.
This looks interesting: COCHRANE STEEL. They look wide enough to keep the tarps down, and easy enough to put them end to end.

You only need WOOD. Inexpensive enough. You just need the proper tools.

Where to buy Backyard Rink Supplies
Some of the most common supplies for a rink are brackets, boards, a liner and a handheld “Zamboni” to flood the ice. I have included two good resources below

If you're going the cinder block route, here are some ideas:

-------------
You don't have to pay for cinder blocks. You can STEAL them. No, seriously, we got some of ours from builders in the area who had left-overs. If it's free, it's for me.
Hope this was somewhat helpful. Regardless, I would ask NEMO, as this is his area of expertise.
Have a nice Sunday!
