Today on the First 40 Miles, for everyone else it’s summer vacation, but not for you.  We’ve enrolled you in summer school.  Welcome to the College of Blister Knowledge.  We’re glad you popped in!  We’re going to do all we can today to prevent this universal trail trial.  Then, on the SUMMIT Gear Review, a water filter that performs equally well in nearly dry creek beds  or rushing glacial run-off.  And one of our first 40 milers will share a wild trip he took with some friends.
