Tips always welcome

I need dental work done soon. If you absolutely loved a walk you went on, tips are always welcome, but as always, I keep the rates and suggested rates reasonable so that everyone can learn about this regardless of their ability to pay (one of the reasons many of my walks have a suggested cost as opposed to a required cost). I also want to travel again soon and learn about plants and ecosystems of countries like the Philippines and Mexico where I have fwends, so feel free to tip the bear if you ever are on a walk and feel extra generous.
