I saw this on Craigslist in the Volunteers section.
"With the snow, high rivers and single digit temperatures, this winter in Pittsburgh has been especially hard on the homeless. Volunteers are need to help our church distribute bales of hay to some of the more popular areas where the homeless tend to camp out, along the river, under bridges, etc. Hay is a great insulator and makes for warm soft bedding, just ask any horse and is still a popular choice for bedding in the third world! Need people with pickup trucks and strong backs to help."
The temperature here, with the wind chill figured in, has gone to ten below zero some nights.
