It certainly isn’t an absolute deterrent: twice, we’ve found deer tracks (one deer each time) and all the sunflowers are gone, and two of the tomato plants.
I’m heading out now for the morning damage report. The electric charger is not working, but we have our technicians working on it. (And yes, this is false color, but it makes the CD look more like a forbidding bloodshot eye, and I hope this is the way the rats-on-stilts (a.k.a deer) see it!
Several of the CD’s there were once on the fence have come down. The fishing line I used to tie them up must be 30 years old (on a reel that’s been over in the barn since 1999) and turns out, it doesn’t stand up to all the sun and wind.
BTW, the item on the tomato stake to the right of the spinning CD is a fence post pounder–a steel tube with a slug of steel in the base, with two handles. You put it over the T-post (or wooden stake) and lift and let fall. Beats heck out of lifting a sledge hammer above shoulder height–a high-risk for smashed fingers plus shoulder tendinitis!
