That is beautiful and I love the name that your grandparents gave it; it gives the place instant history and your family members a sense of belonging. Yea Grandma and Grandpa!!
We're doing something similar with our ranch and I just sure hope that one day our grandkids (we have 4 so far) and great grandkids will love it and appreciate it as much as you appreciate what your family members built.
It's a very meaningful legacy.
