unusual events

manhole covers are blowing off of well...manholes. What would cause such an event? Copious amounts of rain. No joke it has been raining hard for 2 days with no end in sight. And tomorrow snow, blowing, fricking cold snow! Yea! This weather phenom has caused the local wildlife to go a bit crazy. A bear cub climbed at telephone pole today 2 blocks from my house. Yes, I live in downtown of a relative metropolis and yes, I did say bear! He was saved, the power company came and got him. Are power crews trained to rescue bear cubs? And if so, what other animal rescues do they have in their arsonal? Just curious.
