I used to find my caches and then head home to log the finds. By the time I got home, I was at a loss of words and just typed in some lame "thanks" and anything else that i could think of.
Now with the advent of the smartphone, there is no reason not to add a few more lines to my notes. I use my I-phone 3GS (yea I know, I am kind of weird when it comes to getting the latest and greatest) to log my finds right away. And to make it even easier, I downloaded the free app "Dragon Dictation" https://itunes.apple.com/gb/app/dragon-dictation/id341446764?mt=8 to voice record my logs. I make a few corrections and copy and paste the text into the "comments" section of the find.
If you use an I-Phone, give this a try.
