The bike paths in Denver house the homeless during warmer weather. In winter they tend to go to the shelters. Anyhow, the difficult thing is that you have the mentally insane, those just kicked out of their house due to the economy, drug addicts, and alcoholics all mixed together. You never know what you may get. Personally, I just treat them like I would any random person on the street. After all they are people like you and me.

Now why would anyone use strawberry milk on a hot day? Milk is not much of a thirst quencher. IMHO
