[at-l] weight sure makes a difference

[askowronek at mindspring.com (amy)]

Carried my pretty-much fully loaded pack on my weekend peregrination 
around Greenbelt Park yesterday.  I hike the park most weekends, 
usually with some sort of pack.  But not fully loaded - I've been 
building up.

Evidently I have reached the point of "heavy".  Twenty pound pack, no 
biggie.  Twenty eight pound pack, slow hike and sore calves.  Who know?
