I only have 10' width to work with, and am sorta looking at a stop-gap, short lifespan, cheap option.
I moved my mini out of the basement garage. With having lived in Chicago for 20 years or so, Lake Tahoe at 6500' and 8900', rainy Olympia for almost 10 years, etc, never having had a garage, much less a connected to the house garage, it felt good to slip my SUV in there this morning, just because I could. We are in for a week of heavy rain. It will be nice. I will still have to get out to close the door on the way out/ open the door on the way in, but it will be a great change. D will really like it.
I may still opt for something temporary. As is, I still have to get out and unlock and open the driveway gate. I will be looking into an automatic opener, but it may not jive with it being a back-up livestock gate.
