I guess I have been blessed,
The worst I have done so far is to not pay attention to my Mount as it was already pointing at the zenith with the C6RGT that sucker will hit a tripod leg if your observing at the wrong declination and towards the zenith, I heard the motors start to bind but luckily I stopped it early enough to avoid damage.
OH, I almost forgot, I have tripped on my cables and almost knocked over my laptop and scope, I have also managed to hit the side of the doorway with my refractor, it only hit the visual back but all was well.
I do have MS so I tend to stumble from time to time, so far I have been lucky and smart to use a cane to help with my weak left leg. my nightmare scenario is to end up with a relapse that has me falling and knocking over my whole Rig,
