Nuts and fruit (dried or not) is always good, but I need to keep closer track of my intake than they usually allow. I'm that guy that chooses his apples by condition and size, so I can keep my calories reasonably consistent. Before you mock me, it's a system that works.
FYI Clif has some new bars coming out. Has anyone actually seen their entire line - blocks, bars, gels, etc? Their trade show booth is probably 15-20 feet to a side, and even I couldn't graze my way all the way around it in one day. They have a product and flavor for everyone.
