I've been fortunate enough to see them quite a few times in the woods. I have seen females with litters of kittens on two seperate occasions both times in Vermont. One time they hung around the stand for several hours popping in and out of view. We also pushed one out of a deer drive once when I was a kid and it held tight till I was less than 20 yards from it. I've also called them in while coyote hunting when I didn't have tags for the bobcat and let them pass. They will chase a laser pointer like a house cat.
TFox, I think your referring to summer/winter phase bobcats and their coats. They tend to have more spots in the wintertime, their summer coats tend to get more of a gray/solid color pattern and from what I've seen stays that way till late Oct or so.
You guys are gonna make me break out that picture of mine that started the 30+ page thread a few years ago. [8D]
