Years ago, when we lived in Lompoc, CA, we had driven with our boys up to Mount Figeroa just outside Santa Barbara. We were on the way back home when my husband said he saw a bunch of tarantulas crossing the road... I thought he was joking. But he slowed down and I could see that there were literally thousands of them crossing...all going the same way. It was a sight to see, and I am glad I got to see it from the inside of a car, and not on a bicycle!

I have never seen anything like it before or since!
