Big request but exciting!!!!
This is a big request and would require a massive update, however I think it would make the game more exciting and give everyone something to do, the farm can get a bit mundane once everything is done. So my idea is a Farmers fair (country fairground) .. ..
So You would build a bus stop and pick visitors up at the bus stop .. Then take them along to the fair. ( the same way the train takes visitors to the town). Obviously you'll be able to upgrade the bus as you do the train.
At the fair have stalls like; candy floss stall, hotdog stand, burger stand, popcorn stall, pie stall, jacket potato stall and more. Get rewards. Also have rides like a Ferris wheel, ghost train, hook a duck and a bucking bronco where visitors give you coins and vouchers to ride ( but make the ride require maintenance after 10 rides with iron/coal so that we aren't earning coins and vouchers for free).
New machines would be required, a candy floss (cotton candy) machine and a hot dog machine ( this could make hot dogs, corn dogs etc) and Some existing machines would need to make more variety, like more jacket potatoes choices and more burger choices. Also add French fries to an existing machine or introduce a Fryer.
Also so seperate to that;
The newspaper needs to offer more than coins to encourage better and more needed items to be sold.
I think an additional dairy and sugar mill would have to be implemented. The barn would just bulge so all non sale items should be kept in a tool shed ( all farms have them so why can't hayday).
So that's my idea 😄
