In the past three weeks or so I feel like the creepy street dude population has totally exploded. I like to take long walks and it seems like every time I walk someplace now or even ride my bike I run into a gaggle of scummy-looking dudes who harass me for money or say threatening sex stuff. What happened? Is it Spring? Is it the carnival? Two years ago I happily kissed a date on the river walk, beneath the streetlamps. Now it's wall-to-wall blanketed bodies huddled on benches in misery. Are the shelters full? Has the nice weather made people more inclined to camp? Where the city's homeless just less visible before?
