Go down the road a few miles to 16th St, right around the Mass Transit location and the tents and crazy effers are overflowing.
In my little town in North SD County, we more or less are doing the same thing as Coronado. You may seem some homeless attempting to set up long term tent cities, but they aren't around for long as they are moved along after the legal waiting period (post announcing they're being removed).
I regularly, over the last few years, get to see the lowlifes who used to live in suburbs in outstanding neighborhoods attempt to come back to our nice little area and live the good life on the streets, all provided by the misguided do-gooders coughing up handouts at intersections and local morons who advocate for these hardcore homeless. Fortunately, we still have enough common sense people running the show here that we continue to keep moving these losers elsewhere.
How is La Jolla? Do you know?
