I have 2 work sites...
1) A big regional hospital with 3 fantastic cafeterias. I never have to leave the building there. Nor to I want too!!!!
2) A blighted, urban, neighborhood, clinic in the middle of a "food dessert". I never leave the building here too. BUT That means I bring my brown paper bag lunch.
P.S. I ride my bike into work in both places and can bring my bike into my work area in both places.
