My dad told me the story about their Victory Garden in the 1940s. His father had an acre he decided to put under cultivation. It was weedy, so he (my grandfather) spent the day clearing it...with his shirt off.First time I got poison ivy, too. In my case, it was a hot day and I was outside weed whacking some overgrown brush and tall grass while wearing shorts. At first, I too thought, or hoped, it was mosquito bites because they were thick that evening. But it was evident it was poison ivy as the rash spread.
I'm wearing long jeans now when weed whacking the tall grass, despite how hot it may be outside. Not only does wearing long jeans protect me against poison ivy, but it also prevents the mosquitoes and flies from biting around my ankles.

Yep, he came down with a severe case of poison ivy, was in bed for over a week.

They also had chickens! My dad was about 13, and was in charge of the brooder, the chicken coop, and catching Sunday dinner.
