LOL Longtab. Yeah. That kind of stuff. Biological/mental/feeling the rush of adrenalin. I did that stuff allllllllll the time as a kid and growing up. Of course, I had nooooooooo idea what an adrenalin rush was, nor what adrenalin was. I just felt and liked it.
Across the street from the house was a Forest Preserve. In the winters, we would all head over there, when it seemed like the water had frozen over. Also called the Lagoons. This was a project that was dug by hand to put men to work during the depression. Anyway, there was an island out there, that we could never get to. Then and now, you do not swim in that water. Sometimes the ice wasn't all that solid. I NEEDED to get to that island! There was an old comic strip in the newspaper back then called ' Jim Trails' I believe. I learned from one of those, if you lay down on ice covered water, your weight is distributed. I was the only kid that tried. Made it by the way. Still hear the crackling sounds of the ice in my head.
That kinda crap, I continued to do growing up and into SF, during SF and to some extent now. HM..... calculated risk.......
