Mary, I don't do that either.., grass makes me itchy. On the Wave you can reach the middle of the tramp easily from the side.
John McKnight has a great tool he built for tightening lacings. It is a flat piece of alum sheet with a cam cleat mounted at one end. On the other end he cut a hand hold and padded it.
You simply grab the line with the cleat and pull. Jam a fid into the grommet to hold the lacing, and get another grab.
It really does a great job.
One of these days I will have to try and duplicate that tool.
