Driving cross-country for a month can get really expensive and so you think of creative ways to save money. For example, buying grocery stuff and making some meals and snacks throughout the day...
Unfortunately, if you shop here you will probably be spending more money than eating out. The place is expensive, outrageously. They do have a good selection of stuff - local, organic, fresh produce - though extremely limited.
Something else you come across when driving such a distance is a wide variety of people. You'll meet people that live whole healthy lives and inspire you to want to do the same, they are inviting and pleasant to talk to,
And unfortunately, you won't find that here either. The staff sucks. I think they think they're an exclusive bunch.
