Zecora helped me map out some general 'no-go' areas, based on local populations. Poison joke areas, nests for things I do not want to run into, the like. She was even kind enough to mark in the book (permanently, sorry Twilight--at this point I'm just going to buy the damn thing) which plants the Ponies might like the most. Medicinal and recreational ones, for salves and teas.
