When I travel I carry 2 Clif bars with me. IMHO they are the best tasting energy bars, provide me with steady energy during 4 hour bike rides, and during travel they keep me full longer then regular granola bars or candy bars. Also, unlike other protein/energy bars such as balance bars, kashi bars, etc. they do not melt in the heat which is very important during travel. My favorite flavors are: Banana nut bread; Cool mint chocolate; and Black cherry almond.
