Mitch,
Thanks for the review! That is all really nice to hear. I've put quite a bit of effort into the accuracy, so I'm thankful you noticed!
Here's my thinking on the monthly fee - there are constant updates - More layers are getting added (working on HOV / Trails right now), the data is getting updated, and people want an up to date map.
The tool is really a hunt planner - the idea is that I might plan a hunt a week, month, or year in advance. This tool lets me save those maps and come back to them at any time. Up next I'm going to add some stuff that lets you plan group hunts.
So I figured people would want to get in there and tinker with it all the time... not just for one map.
Does any of that make a monthly fee more acceptable? I go back and forth on it - mostly because I see how much work I put into it month to month

I'm biased.
