Wow! I was there on Sunday just after 12:30...a bird acquaintance told me that he saw a coyote earlier in the morning in the field where the platform was...kind of scary
They can be mistaken for simple dogs...I remember a few years ago that coyotes were travelling from high park to humber bay..(a pair if i recall and mangy too).
You can warn folks all you want but they dont' listen and like you said..until an incident happens, that's when it is an issue.
I warned a few people in High Park when I saw the coyotes along the path and one person said "oh i'm not worried my dog can hold his own"..hmmhmmmm...keep thinking that buddy.
I hope I am lucky enough to capture one on film again, they are like ghosts... I love it.
