My wife grew up on Lake Tahoe every summer through about age 18. They had a little teardrop trailer and camped all summer long from the day after school got out until the day before school started again. Water skiing every day — without wet suits! It must have been a great life!
I grew up on a lake in the Summer months, too! My Grandparents had a place on Big Silver Lake in Wautoma, WI. Mom and Dad would drop Sis & I off for the Summer, and (maybe) visit on the weekends. ;)
It was/is a great life for a kid.
