While I’m sure the first image to come to mind for most people is a small enclosure meant for the use of the family dog, or a husband on the ill tempered side of his wife, to sleep in, doghouse may also refers to the cab portion of a truck body, less the bed and front end componants. Still, a doghouse isn’t so big as to require the ‘wide load’ treatment, and they aren’t so heavy as to be difficult to haul- a pickup truck has enough oomph to do it.
When it comes to not running over a snake ‘had to’ is a matter of perception. Your specimine would have been full grown, at four feet long, and should have still been in hybernation for another two months or so. Plus it’s only common to a few counties along the Mississippi river in Missouri.
My first question about number 3 is do 56 and 281 even meet- they do, in a T intersection. If that wind turbine blade were on a flatbed truck turning left, I could believe the swing would threaten other vehicles on the road.
I’m more in inclined to wonder if you actually went to the vet on a Saturday. I’m married to a vet, and Saturdays are usually chock full of everyone who couldn’t get in during the week. It’s a madhouse. My wife’s clinic is only open till noon on Saturday because of the chaos.
