Rocky's Burger Bus is exactly that.  A converted old bus parked next to the Crossroads Market.

It is open year round but only till about 3pm to serve the lunch hour crowds. The burgers are big fat and deliciously juicy.  Several choices to choose from with/without cheese etc. Fries are big steak-cut style, crispy on the outside and soft fluffy in the middle.

Swing on by to enjoy a burger from a very unique burger stand.
