Have an appointment at the VA on 'pill hill' myself soon..
connected by the skyway bridge..
VAMC/ DAV van gets me to and fro. from the coast.

FWIW, 4 miles
You could probably do your commute on a folding bike
and bring it inside when you get there..

in town there, Clever Cycles has some nice practical bikes.
other shops have different types, perhaps you go for a racier type.

definitely test ride a bunch, it's an aquired taste for bike type choice.
