Level upgrades impact on payouts! (Thanks to TSTOAddicts)

I'm at level 17 for the center. Think I'm still going to keep it there for now since I have plenty of corn. Maybe once I have the farmer's market I think about upgrading more. But I agree, there doesn't seem to be much benefit in going higher than 19.
Haven't got the sprayer yet but hope to tonight.

Thanks again LP for all the guides. They really help in planning things. :D
