Meandering thoughts from a couple of very long runs. A brief recap of a solo self-supported 50 kilometer run and a Patriots Day hike on Mt. Greylock. Seth Godin commentary on people being bad a making predictions. And a 10-minute recollection about marine geology research from my graduate studies at the University of Hawaii. A simple sound triggered the memory from more than 25 years ago. Happy trails and Aloha.
