While in the Swedish military I was also trained as a Ranger , but also as a motorcycle ordonence...we trained one late fall night = very dark, driving on dirt roads without lights....I had a problem w my bike and when I got going to catch up...I sped up a bit....suddenly I came to a Y in the road...I got off trying to see tracks, but couldnt pick them out , too many there....picked one direction...after a while I felt like "this must be wrong", so I stopped , was going to see if I could see any fresh tracks again...as I parked the bike , I realized there was a chain strung across that road at abv 3 ft ht! I`m glad I stopped where I did....that could have been really bad
