answer:Mine was weather related too. Hiking in Colorado near a 12,500 foot pass, it started to drizzle, then rain, and then a deluge, so we headed back to the car. There was lightning striking about a mile away on the ridge tops, but we felt safer being in the trees and off the heights. We made it to the car, and as we were shedding our soaked clothes, lightning struck about 500 feet up the trail we had just come down. WTF!?!
