The coolest thing I did this summer: During a family vacation in Hawaii, daughter Gaby, son Eben and I saw the spectacular sunrise from the 10,000-foot-high crater rim of the Haleakala volcano, then bicycled 23 miles downhill. Nature's roller coaster, with a stop halfway down for macadamia pancakes!
Two of coolest things I'll be doing this fall: Meeting with students and talking trash in October with the freshman of Rowan University in New Jersey, just across the river from my hometown of Philadelphia, and at the Georgia Institute of Technology in Atlanta. Both schools have adopted Garbology as their freshmen reads.
