About 50% of my riding is in a rural, farming area with no leash laws and I've had my share of run ins with dogs. Most of the dogs I encounter in these areas of no leash laws are OK but there is that percentage that isn't OK. This post really isn't about the dogs in the rural part of my county. Actually my experiences with dogs in that area are worth a post on its own.
Further south there are riding trails and a typical urban environment, complete with leash laws. A few hours ago I was on a road just a few hundred yards from "mile zero" of the local trail when out from a trash strewn yard with a trailer came three very large pit bulls on an intercept course. The were big enough that they weren't very fast and a fear fueled boost to 30 mph+ put them behind me. This is in an area where there are lots of bikers who aren't nearly as fast as I and I'm pretty sure it would end badly. I called the county animal control. One of their question was the exact address which, for some reason I failed to note. I met animal control, put my bike on the rack and led animal control (female officer) to the yard. The officer turned into the yard with the dogs still loose and I went a few hundred yards to turn around. When I got back, the animal control officer was cowering in the truck as this huge black guy was in the process of going NUTS! He came up to my window and told me that I was going to get hurt. The logical thing seemed to be to leave and call the cops. Turns out that the animal control officer already had called them to protect her.
When the smoke cleared the guy was not in jail but it will cost him $500 and very probably the dogs since this isn't close to the first complaint on them. The sheriffs deputy suggested that I not ride by that location for at least a few months.
I live in Florida and have a weapons license, sometimes I'm happy for that.
