I meant to post this to this thread a bit ago but forgot...I was running a new (and, hoped shadier) route and a GIGANTIC dog came flying off the front porch at me. I didn't even have my bento box with my little rocks (which this particularly large canine would have laughed at)....it was going to be hand to paw combat for sure. He was doing that bark/growl/snarl thing as he flew toward me...I spent the last few moments of my thinking of the very little time I had with my new bike....
and then the beast stopped dead. A mere foot in front of me. I opened my squinched up eyes, relaxed my clenched fists, tried to unkink my body that was braced for impact and stood face to face with the snarling beast. He was growling menacingly at me, but made no move to come further. Then I noticed his collar and recognized it as an invisible fence collar. I thumped myself on the chest a time or two to restart my heart, and jogged on.
There should be some sort of warning system for pedestrians, cyclists, and joggers passing houses with these things. That was just WRONG.
