With Memorial Day weekend just hours away and road trips on the horizon, I thought it appropriate to share this random little gizmo with you. It’s a function on the comptroller’s site that quickly computes the mileage between every city in the state.

What makes this one different than Google Maps or MapQuest is that you can put in up to nine cities on your route—and should this be work-related travel, it will also calculate your reimbursement based on a rate per mile you enter.
