In 2009, the Romneys sold their primary residence in Belmont and their ski chalet in Utah, leaving them an estate along Lake Winnipesaukee in Wolfeboro, New Hampshire, and an oceanfront home in the La Jolla district of San Diego, California, which they had purchased the year before. The La Jolla home proved beneficial in location and climate for Ann Romney's multiple sclerosis therapies and for recovering from her late 2008 diagnosis of mammary ductal carcinoma in situ and subsequent lumpectomy. Both it and the New Hampshire location were near some of their grandchildren. Romney maintained his voting registration in Massachusetts, however, and bought a smaller condominium in Belmont during 2010. In February 2010, Romney had a minor altercation with LMFAO member Skyler Gordy, known as Sky Blu, on an airplane flight.
