Why trampolines are dangerous in Michigan

My sister Chris who lives in Michigan sent this! We have so many deer in Aura in the summer and they often come very close to the house. This made us laugh because they feel so at home around the house. They ate apples in the fall right outside the door and will often come right up to the garden at the edge of the house to nibble. You can hear their snort from inside. Its a bit scary at times.
