"So I ask: Do you have a computer based log? "

No, as of yet I do not use any electronic log. I know they have there benefits, from what I read anyway, but I prefer just me and the notepad. I believe it can be much faster and easier to get to or put away. I believe that you will better achieve that connection you're looking for by keeping a log when you use writing. I buy the cheapest notebooks I can find and use certain colors of notebooks for certain seasons and such. It's not hard to keep them from getting wet either, and even a good washin from heavy rain, if it ever happens, doesn't mean lost info, depends on the ink you use or if you prefer lead. Thats only happened to me once when a window wasn't rolled up before the rainstorm.
Maybe take you a pocket-sized notepad to jot it all down and expand on it later at home in your fisherman's journal.
I guess it's a variable factor. Take as many variables out as you can, lord knows they're infinite. If it's not necessary, leave it out.
Knowing about how the elcronic logs work give you a better idea of what to include when starting a hand-written journal.
