About 2 years ago, I somehow managed to get on the monthly distribution list for a guy named Bob Webster. He is a techno-geek-sailor-aviator-mountaineer-outdoorsman sort of guy that apparently has a ton of free time to travel the world and do really fun things.
His monthly emails include some great photos of his travels, and some cool information about space, astronomy, aviation, technology, etc.
It's available as a monthly email, but can also be viewed as a web page. Here is the update I received today.
