I visit High Park a lot, and this past summer I bumped into a couple (one of each) without their plumage, and I found out how much faster one can put their clothes back on when faced with a big white lens. This was a well traveled path, and as someone else mentioned in an area where the warblers tend to reside. As I passed these two love birds, I met a mother with three small children coming the other way, who would have been taught a early lesson about the birds and the bees. I've seen the male lurkers, and I've found that the camera tends to move them along pretty quickly. I've been told that there has be an increase of theft from vehicles within the park, and I've noticed that police have increase patrols, but they never step out of their cars. I noticed that they did increase the bike/horse patrols late summer, hope this continues.
Signs warning that photos of non nature lovers (does that work) will be posted on the net may lead to problems for a lone photographer. Poison ivy maybe?
