I would go back two hundred years. This location, Middle of Spring.
I would collect as much gold lying around the place as possible. I would start a bank account in the Bank of London, before the American Revolution. I would start the account based on a portait resemblance of me, and a series of 12 codes, left in the Vatican, Bank of England, Swiss Parliament and Sandringham. The existence of which would be known only to the English Royal Line, and the Head of the Bank of England.
Then I would come back, and go collect.
