My thoughts as well!
Pity you don't live near me (kind of glad you don't!) as i have a faulty 'sacrificial' trail camera you could have put up to be filmed by your new one.
Dog walkers, not all are bad, just a few bad apples, as an example i was fishing yesterday, i accept as i am difficult to see wading in the river sometimes a stick will be thrown in for the dog, then the owner realises and will apoligise, not yesterday, dog came bounding in, i tried to shoo it out but that just encouraged it, she came along with a friend, i didn't say anything but you could see she was really annoyed i had shouted at the dog, when i got back to my pickup i assume it was her who left a load of rubbish on the roll top cover!
My late friend dealt with the problem in a different manner, guy threw stick in front of him in the river, spaniel jumped in, my mate asked him to please not do that, and my friend walked downstream ( my late friend was ex marine and 6' 2'') to fish another area, along came the guy again, this time threw stick at my mate, my mate got out of the river, didn't say anything, walked up to dog walker, felled him with one punch! i said what did the guy do? my mates answer was 'nothing, he just stayed down bleeding!', just to clarify my mate was not a gun owner and i do not condone what he did!
Cheers
