My theme is Wilderness Adventure
. Minfigs get away from it all, with fun and fresh air in the great outdoors!
1. The large set would be just like Rocky River Retreat (or even a Legend):
A cabin, mountain, river, brick-built pine trees, rope bridge, horse and truck with boat & trailer and appropriate minifigs.
2. The medium set would be a campsite, with tent, fire, canoe, hiking gear, appropriate minifig or two and bear!
3. The small set could be a fisherman in a boat, with an alligator or shark.
