I don't want to sound overly optimistic but after Luis in September, 98? we went to Sint Maarten just a couple months later (December-January). Most buildings still did not have roofs and the Belair, where we stay, sometimes lost electricity/hot water/ and air conditioning while we were there. Divi, next door to Belair was almost completely destroyed.
I am not minimizing the devastation of Irma but before we suggest how long it will take to rebuild, let's get accurate information from all legitimate sources.
