This is second time he has been bitten in the last 3 years. Both times it happened when things were warming up. Mi. rattlers move to higher ground in the fall to hibernate and have little ones, so I think they're hibernating in my field stone retaining wall (on the south side of the house) and that's where his crossing paths with them.
