Question

what made aunt Mabel to change the schedule of staying at grandparents home​.​

Answer 1

I sincerely hope Aunt Mabel was a full-time homemaker when her parents came to California, since they stayed seven months! Grandma kept careful notes on their ramble across the range, full of where they stayed, where they ate, and what they saw. But not one word about the whole time spent in San Bruno. It’s a mystery.
