I armed my self with gloves and and my weed pulling tool . In just over 2 hours I filled 3 garbage bags with weeds . It was very hot out , and I loved it . I do n't know why , but being out there working and sweating like that makes me feel more alive somehow .

Working outside in their garden while working up a good sweat .
