So travel is an opportunity to catch up on rare books? I travel with reading material, but it is really just to fill the idle time with something I can do sitting down. Love to sleep through the whole thing, but never seems to work out that way. I remember flying from New York to Paris overnight with the lights out, watching the minutes crawl by. Anyway, whatever circumstances allow to make minutes go by at least in realtime is welcome. Actually, popular crime novels are one favorite way. I know I can download those.
