Don’t post that Instagram. Send a postcard instead.

On a warm afternoon at Isle Royale National Park in Michigan this September, I found myself with two hours to spare before my flight back. It had taken me three tries to get to this national park, which is only accessible by boat or sea plane, and I was wiped out from my morning hike. Instead of venturing out again, I bought a beer from the camp store, settled in at a plastic table outside and started writing postcards.
