Arrival of Boston street sweepers heralds spring

I'm the original anon poster. There aren't townies in my neighborhood, so I have no opinion on what they do or don't do. Typically I see tourists and students tossing trash on the sidewalks and in front of residential property. How can I tell they're students? They are typically young guys with large backpacks walking in groups of 3 or more. While there are many college students in this neighborhood, it's not considered a college kids neighborhood like Fenway or Allston. Most of the students are pretty well behaved, though it just takes a few to ruin it for the rest of them. Re: tourists - if you can't tell who is a tourist and who isn't, and by tourist that includes suburbanites, then you're not an observant person. As for who leaves behind dog crap bags, I've never witnessed anyone do it, so I don't know. It's a fairly well to do neighborhood with many 'professional' dog walkers... maybe they are responsible. Maybe it's the db who drives the BMW and parks in front of the fire hydrant. As for yuppies, isn't that an outdated term? I thought that was played out in the 80's and 90's. If I see someone tossing garbage on the sidewalk, I say something; if someone parks in front of a fire hydrant I report it; if I see a drunk frat boy pissing on the side of a residential building, I say something. Lived in Boston for nearly 20 years now, same neighborhood, and again, these are just my personal observations.
