My husband and I ran an errand to our state capital, Toluca. When we accelerated onto the 15 toll road, right there on the stretch just before the turn off to Valle de Bravo, we ran smack dab into a cloud of migrating monarchs. We slowed down, put on our blinkers, and started counting: we spotted at least 100 butterflies between 10:11 and 10:16 am on March 21. While some were flying high, others darted dangerously low across the road way. Others were already dead on the road. They were most likely headed out from Piedra Herrada, and they were flying straight north.
