Look forward to your fieldnotes! I only haven't done any because at a rough guess there's about 150 sites on here I went to before TMA existed....
Got some catching up to do, but I'm too busy trying to keep up with recent trips!!!
Take & post a few pics to save me scanning mine!!!
There's no way (famous last words) you'll miss it & shouldn't need the GPS (but it won't do any harm LOL).
love
