I might have some things for the long-term loan department, but I've already put together a care package for someone else whose gear was stolen. Contact me via PM to see what the situation is.
Hope (fingers crossed) you had homeowners or renters insurance, which might cover some of the losses.
Rob, as a born and raised New Yorker and a very frequent visitor to Brooklyn, where my daughter lives, I gotta tell you that in real life it isn't always possible to get valuables, especially bulky valuables, out of the car and into a safer place. Sooner or later, the vagaries of parking and the demands of schedules will force you to leave stuff in your car. So give 'em a break!
Carlitos, sorry to hear you folks got so badly burned.
