My recommendation for a good murder mystery is "Vindication". It actually takes place right here in the Villages. The author's description of different places is amazing. The plot is good also. The author is H. Terrell Griffin. The book came out this year.
We only insulated our Garage door, but I do have someone that would rent the machine, & he would have to do 3 Garages & the cost of the material & labor would be about $ 300 a Garage. I did want to insulate ours but I needed 2 others to go in with me.
