On July 5th, 2004. Bob Bolton and I climbed Lassen Peak in California. When we arrived, only two others were on top. We were there about an hour and during that time 34 others arrived and so we headed down, meeting about another 100 or so who were headed up. Talk about crowds, this peak gets em.
This pic only shows a few of those who were soon crowding the top. Avoid this peak on a summer weekend if it has good weather.
