Any tips on completing Sunny Meadows on 0 evidence but quickly?

I've been grinding to unlock all of the "50 win" badges on the bulletin board. I completed the campsite one ages ago; then (more recently), I completed Point Hope, the farmhouse, and Nell's Diner challenges (in that order). I've decided to do Sunny Meadows before tanglewood to give myself a break, but man I hate this map. Even while playing on restricted version, the map is still humongous. Any tips?
