List of prop ideas:
rakes, baskets, watering cans, umbrellas, scarecrows, piles of sticks, leaves, campfires, thick boots, mushrooms, huge brown sacks of nondescript content (maybe it's potatoes, mud, carrots, hay??), all kinds of vegetables and harvest (wheat) and pies!, acorns fucking everywhere, big wagons/carts, sunflower, elaborate black metal fences (modular).
Also leaves everywhere. Especially on stairs. People seems to love taking photos of that!
Is what I got from 10 minutes of looking at google images with various search terms.
