Outside of the U.S., I've chased snakes & spiders in Mexico, Costa Rica, Suriname, Sri Lanka, Malaysia & Borneo, but I mostly look forward to continuing to explore the amazing southwestern USA with a focus on the Madrean Sky Islands. There is no country as bountiful in terms of fauna, flora & landscape as the United States.
