How long before Manhattan is underwater ?

Don't get any ideas -- I have already purchased an option for the first Manhattan Gondola Service designed to take Big Shot Wall Street Executives to work when the streets are flooded from climate change sea level rise.

According to the lower Manhattan tide gauge (below), it appears that I will not live long enough to get that expected Wall Street flooding.

Therefore I have decided to sell my gondola option, in a package deal, along with my 25% ownership of a bridge between Manhattan and Brooklyn.
