Campsite or bridge, depending on how badly I need the bridge! The campsite because you never know what future villager you might find! Bridge because it helps you get from place to place.
Omg, me too! I had this grand idea of how I was going to surround the fountain with lots and lots of flower... but I built to too close to the train track and rocks... so the plan failed. I haven't even thought of demolishing it though. It's my first PWP and it will stay there forever.
