Beyond that, I simply can't get over the fact that I'm paying Garmin over $1000 for the privilege to spend my time and gas to make something that directly benefits them. So if I do 3-4 trips to a lake over a summer, then upload, I'm not providing much in terms of mapping, but I'm giving a very clear map of where I fish.
It would take 1000s of hours to map just one of our big lakes (sounds like the panoptix 'ducers make it go much quicker, and will be one more reason to get the upgrade for me). Up here we have many large lakes and very few people. AlgaeKilla, you're right, I could choose to take a generous approach to it, to a great extent my outlook is specific to my location.
