I think the main problem is with the mirror. While your driving have one of the son’s remove that mirror. While you’re still driving ( preferably across the Theodosia Bridge) have your son put all of his arm and shoulder muscles into motivating said mirror beyond the side of the bridge and into the lake that the bridge crosses over. Since you’re going East anyway (to work on the house) it’s only about 15 more minutes to Gainesville, Mo where there just happens to be an Oreilly parts store and they will have a replacement mirror for the one that got lost in the lake. More than likely it will not have that annoying thermometer display built into it. If you need to know the temp outside, while your driving, it’s really simple. Just roll your window down and stick your arm out. If you pull your arm back in and it has a nice crunchy black texture to it you’ll know it too hot out and leave the window up while you enjoy the vehicle A/C.
