Long time back, 64 or 65, I was in Christoval TX during one of the migrations. Was on land bordering the east side of the Concho, and the monarchs were so thick the trees looked golden. Large pecans and oaks had limbs so loaded with butterflies that the weight was pulling the limbs down to the ground. You could walk up to a limb and actually scrape large handfuls off the trees.
Had to be a heck of a sight, any pictures?
OP Great pictures and I like the Cedar cover scent idea
