I hope this makes it through, because this is one of those categories that I will go out of my way to visit someone else's waymarks. I certainly visit any waymarks in categories that I am interested in whenever I'm out and about, but I rarely go significantly out of my way solely to visit someone else's waymark. There are a few categories that I will do this for and this will be another one.
I don't ever anticipate doing very many of my own of these, mainly because I'm not that great of an artist, but I can think of some that I will do. Probably mostly lighthouses and church buildings, but we'll see. It will be fun just to reassess each area I am waymarking in and decide whether there is something there I would like to sketch.
