Disturbing Dog Kicker Incident at Wyman Park Dell

This afternoon I was walking my dog at the corner of 29th and Howard near the Wyman Park Dell in Remington when a bearded man who appeared to be about 250lbs in his 30s approached me asking me if he could pet my dog. My dog was very alarmed by the way this guy was trying to approach him and was not letting him near him. This went on for about 30 seconds as I twirled around as my dog tried to hide behind my legs. I finally said politely that it doesn't appear that my dog is comfortable with being pet right now and apologized. The man then kicked at my dog (just barely missing), which caught me completely off-guard and when I realized what I just witnessed asked the man if he just tried to kick my dog. He said yes, let me pet your dog as he continued to try to get to my dog. Starting to panic, I asked him if he was out of his mind (to which he replied yes, let me pet your dog) and I started quickly walking away down the street the opposite way, and when I noticed the man following me I started to run. He ran after me and my dog for half a block before giving up and turning around.

I am horrified by the idea of what this guy would have done if he got close enough to my dog to pet him...

Has anyone had any experience like this in that area? I get the feeling this isn't a one-off with this guy.
