Something happened to me for the 1st time. On the way back from the Coke ovens area, I came across a guy walking and talking on his phone, so I knew something was up. I stopped, and he ask if I had any tools. Turns out he was in a General with 3 other guys, and they had broken a tie rod end In a narrow rock wedge, blocking the trail completely (not that I wouldn't have stopped anyway). They had a spare, but weren't able to get the jam nut loose with what they had, so I lent them my pipe wrench.
10 minutes and they were moving again, and one of the guys insisted on giving me a $20, even though I told him not to worry about it and pay it forward.
I've seen 1 or 2 being towed or worked on, but this was the 1st I've came across broken and stranded.
