Sometimes I want a snack, and rather than stopping myself I try and earn it, so I try and find a store that is in a reasonable walking distance and walk there for it. Of course I like walking too so this all ties together. Anyway I found a place to walk to that is about a 10 minute walk from my current place of employment En Route at the Princeton Junction train station. It would be about a 20 minute walk if I didn't know about a short cut through the swamp behind my office building.
Plus I got to see a bunch of cabbies standing around at the station telling jokes in some other language.
