I take a lot of pics from bridges, and while I'm very careful, I do find myself thinking about what I'd do if a knife tumbled in.
My best ever escapade along these lines. My wife and I were on vacation up near the Great Smoky Mountains in Tennessee. We went rather early in the season that year, before the majority of the tourist crowds. We were driving on some less traveled roads in the less popular areas, looking at the different wildflowers that were in bloom at the time. We stopped by a bridge over a rather wide mountain stream (Cataloochee Creek to be exact) for a picnic and some leg stretching. There was a bridge over that stream - steel girders and all but the bed of it was like slats with slots between them. I was walking across that bridge and was near the far side when I dropped the car keys. Why they were out of my pocket I have no idea. Sure enough, they fell through a slat into that stream.
I walked back over to where my wife was (at the car) and she had not brought her keys with her. This was many years ago, in the 90s, before cell phones (shocking, I know). We had not seen a single car drive by in the 30 minutes or so we had been there.
So I took off my shoes and socks and rolled up my pants legs, and started wading across that stream to where I thought I might have dropped the keys. That water was COLD - coming off the mountains in early April, and the rocks I was walking across, while mostly smooth, were still painful to bare feet. The current was pretty swift, so I was afraid they had washed away and would never be found.
Finally, after wading ALL the way across that COLD, wide, rocky bottom mountain stream, I actually found the keys, in about 6" of water, not 5 feet from the opposite shore. I had mistaken how far across the stream I was when I dropped the keys, and didn't realize I could have just gone across the bridge, bent down, and picked them up.
The best part about that story - when I got back to the car and put my clean, dry cotton socks on, that was one of the BEST sensations I have ever experienced. To have my poor, stone battered, ice cold feet once again wrapped in soft, warm cotton.
I still have those socks.
No knife content, sorry. If it were today, a Victorinox Mini Champ would have been on the key ring, and my car would not start because it uses an electronic keyless fob which would probably not have survived 30 minutes of immersion. Back then, it was metal key and worked just fine.
Here's a tribute to those that have gifted knives to me or GAW's that I 've won. I have a total of 62 knives left and all but 3 of them came from the generosity of Porch Dwellers. I also had to sell some of the knives gifted to me but the folks that had given them to me had no problem with that at all and were just happy to help. I can't help but think about all those that rallied around my buddy Bigbiscuit and his family in their time of need. What a great place to be a little part of.
Really hoping I never do though!
