If they did,it would almost have to be a coyote male with a female wolf,I think both anatomical and social differences would keep it from happening any other way.I can't say yay or nay for sure, I don't have the experience.Historically they have stayed separate types of the same species for quite some time,it must be genetic ?
I think the 60 pound coyote is a result of good eating.I once saw and shot at a male coyote in heavy woods several years ago that would most likely match Sheri's fairly closely in size.The female I killed several years ago was scrawny compared to the other 4 I've seen in this state,39 pounds.It's not that far a stretch from a 39 pound female to a 60 pound male.While not common,I'm sure there are a few of that size here and in other Eastern states.
By the way,the largest recorded coon killed in this state back in 1880+ weighed 65 pounds,just to put some perspective on what can happen within a given species without interbreeding.
