We did the cottage thing in Canada when I was small... until my mom's sister moved down to Margate, FLA in 1971. Canada with cousins on my mom's side. Fishing in the Detroit River for walleye or Lake St. Clair for perch... with my mom's brother and my cousin David.
Only one brother and sister so not a direct large family...
However...
My dad has 8 brothers and sisters. I have cousins coming out of my ears from that side...
Those 20 acres between Hart and Shelby...? A summer camping trip there for two weeks? Populated by at least 40 aunts, uncles, cousins, mom & dad & sis & brother & grandpa & grandpa and we're all playing volleyball, baseball, local canoeing, bonfire with 10 campers or tents surrounding it, or a trip to Lake Michigan or to Sleeping Bear Sand Dunes and with that many cousins coming out of my ears...
Pandemonium.
Every single year.
