I've been happily section hiking for several years in my Chaco sandals. This year I'm looking at the PA section from DWG southbound. Am I nuts to do it in my sandals? I've been fine in the other sections I've done and have over 300 section miles on them. Just getting worried about all those "millions of rocks all pointing straight up" stories about PA. Anybody here done PA in sandals, or have stories?
