I learned that waymarking is a great way to re-discover those interesting locations all around you which you never even really noticed before. To me it has rekindled a desire to explore my surroundings and act like a tourist in my own town. It has been so long since I have visited some of the places, that in a way it is like seeing them for the first time. Also, it has definitely made me become more observant of locations as I drive anywhere, and all the much more interested in local history.
And a few things I've learned about which I had never heard of before waymarking are zinc headstones, Woodmen of the World, Tim Horton's, and the Independent Order of Odd Fellows.
