Find out who owns the land. Maybe you'll come across some clues.

Arrive around lunch time. If you see construction workers taking a break, chat them up and ask what's going on. Building purpose, owners, etc. A lot of times they know things. I've gotten a lot of sales leads by doing this.

EDIT: I will mention this....Amazon is effectively trying to re-make the distribution of their goods across the last mile. They think the job can be done for even less than USPS with their huge subsidy (or maybe they think that subsidy is going away soon). It's dirt cheap to start a distribution center - like $10k. But if you really want to make big money you need to be able to process and deliver a lot of orders. 60 miles as the crow flies from Chambersburg PA is about 3 million people.
