what are some examples of the "bad" or heavy guidebooks?
Back in the cheap days, I would photocopy most guidebooks (I know...BAD me). But that allowed me to pull out selected pages easily. Most parking spots in l'worth only had a couple pages of routes accessed.
If the weight of the guidebook is too much, photocopy the pages from your store purchased guidebook that you need for the day. 85 sheets ($8.50) would cover the icicle area. A cheaper option is to make your buddy carry the guidebook and the beer.
