I haven't gotten any suggestions. It probably has to do with the fact that I spend most of my time on the island catching bugs for my ever expanding house LOL.
Wait until 7-9PM and after 11PM
all the rare bugs comes out there, you will get rich FAST.
Also cut down the trees in the middle of the island, it makes the efficiency better.
We are DYING for one of our neighbors to suggest the police station. The last request was from Isabelle to upgrade Town Hall (my daughter went modern, and it looks awful in our town). She has been doing some miscellaneous ones like the fire hydrant, etc... to see if someone will get their behind in gear and request a police station. It's been over a week since we had a request.
