A license to walk the streets, paths? No not a license to be a Streetwalker. But a license to be a street walker. Actually a sidewalk walker though sometimes if a sidewalk is blocked you walk around it by walking in the street close to the curb. We could have separate licenses for sidewalks. Double dip. Then a license to walk on someone's private property. A license to enter a public building. Think how much revenue cities/states will receive? You can tax 'em to the hilt. Local tax, city tax, state tax, federal tax, exercise tax, just-for-the-he** of it tax. For every one who walks anywhere anytime 24/7? A mother lode of revenue just sitting there waiting to be tapped.
