toedtoes; Exactly!! It all comes down to common sense! We were at a Northern Coast campground, dog was tethered up, being cool, DW was in the kitchen fixing vittles, I went in to mix a drink, came out and the Ranger was just driving by, he stopped because dog was unsupervised and walked up to advise the rules.
I explained and thanked him. He actually told me to give him more leader so he could follow me into the trailer when I needed!! Hence now the 40 foot of flat stock tied off at what ever length fits the site,you can see in my photo that I can adjust length at either end by double or triple looping the anchor end so as the dog does not have to drag a huge knot around or I can just make a large 20 foot loop and attach the six foot leader.
