As it so happens, yesterday I got an email from web-based flyfishing magazine called Western Flyfisher (
www.westerflyfisher.com). I certainly like the idea of a free fishing magazine (which this is). Only downside is that the file is 10MB so it's a long haul on a dial up. Anyway, I'm flipping through it and on p. 25 of the Jan 2001 issue there's an ad from Simms on wading safety. You have a choice of topics to click on and then the option of downloading videos.
One of the topics is "Handling Log Jams" so I had a look at that. I must say I wasn't convinced -- the log was medium sized and so was the flow. The advice to (a) ditch your rod and (b) swim over the log, don't try to dive under seemed better if you can apply it.
After seeing the video, I thought some more about my buddy in the Malaysia jungle river. I think in that case "you die" is the likely outcome.
