This is the time of year when not having/using air conditioning pays dividends. I don't do anything different on my commute than I do on any other summer day, except ensure that my water bottle is topped off for the ride home.

"Let us hope our weapons are never needed --but do not forget what the common people knew when they demanded the Bill of Rights: An armed citizenry is the first defense, the best defense, and the final defense against tyranny. If guns are outlawed, only the government will have guns. Only the police, the secret police, the military, the hired servants of our rulers. Only the government -- and a few outlaws. I intend to be among the outlaws" - Edward Abbey
