This will generate a heat map of your geocache finds (see image on the right)- you'll need to be a geocaching.com member with a 'My Finds' file to use it
--- Now with added Michael Fish!
Update for 2023, server move and slight map tweak. A bit more accurate and more of Ireland covered (unless plotted under Mr Fish) - let me know if anything looks wrong.
Old image still showing up after a newly generated heatmap?
