Civil Airfield Lawrence Municipal Airport (KLWM)

One of my favorite places in the US. Very attractive costs for super expensive Boston (try going to Bedford, you might not want your airplane back once you see the fee) and Falcon FBO is a fantastic FBO, incredibly accommodating. It's the opposite of current money grabbing FBO trend in the US. Only caveat: in winter, the runways often do not get plowed and turn into skating rinks which effectively closes the airport for weeks.
