Redneck Parrotheads:I'm digging a Birding Trails cat because I think those are marked differently than how Birdwatching Locations waymarks are marked. It creates a different experience.
I'm glad you posted that, I was about to make a rather pompous post about it being redundant, as we already have "birdwatching locations". 
Cat would need to give clear instructions about differentiating between the two, and the "locations" cat should be updated to include a cross link if/when the new one is published.
