We were riding at Bridle trails State Park in Bellevue, WA (there's a similar thread in that area as well) and we came upon a maintenance guy clearing the trail with a leaf blower. I expected very bad things to happen but LT was like a rock. No problem at all.
Video of the incident is here Bridle Trails State Park in Bellevue Washington
Two days later LT and I came in 3rd in a mounted orienteering event.
I'd say he's a keeper!
