I based my airplane here for several years. Tower personnel are generally
excellent, very accommodating in spite of ever increasing carrier options
(Southwest). Mid Island Air is a great FBO - used them for fuel, service,
and tie down. They'll bend over backwards for you. I earning my private,
instrument, and commercial here. Felt a lot safer flying into/out of ISP
than HWV or FRG, especially during the summer months. Generally
FOK or HTO are avoided unless you have some specific reason to be
out east along the south shore of LI (hi Paris, Gywenth, John, ...)
