I would think that you could have gotten as much protein as you need from a vegan ride. Did they have any beans? Protein is also more of a recovery item and not essential for a 65mile ride. You don't really break down and use that protein until it comes time to repair his muscles. Perhaps there was some other problem not the fact that they were forcing you to eat local vegatbles and things that didn't have to travel across the country on a truck spending 1000gallons of gas
