Many years ago , a group of friends went to the lake to camp, fish , ski, etc. Arrived late at nite , threw the old fashioned cabin tent on the ground , crawled into the sleeping bags, on top of the tent, next day did our lake thing, that night setting around the camp fire, we started noticing shadows that seemed to be moving, someone shined a light , THERE WERE HUNDREDS & HUNDREDS OF TARANTULAS walking through the campsite. evidentially it was migration time and had been for a week, this was a nightly occurrence for the long weekend. Glad the tent had been zipped up that day when we finally set it up
