The three American companies that I love most are Apple, Tom Bihn and Lärabar.
This is a plug for my favorite nutrition bar. I just discovered that Costco sells cases of Lärabar - so I just picked up 6 for the Winter stash! I have a very restricted diet and have never found an equal replacement for Lärabars. Everywhere that my Macbook and Tom Bihn luggage travel, so do my Lära Bars!
