Glad that you are OK. Walker has gotten me a few times when I am doing some work around him,In the thread about my grandson riding him the last sentence is, "he travels around like he does normally when other people are in his area other than just me" after I posted I realized most people would have no idea what I meant by that statement. If it is just me and him he is real possessive of just about everything,and if I need to do some repairs, changes, etc, he is a pain to work around. But if there are more people around he is just as sweet as can be. I still keep a close watch on him because he can hurt someone even if it is not done intentionally. I'm surprised Dudley has never rammed you before, hopefully he never does it again.
