Ron a NIMBY? How on Earth did you get that idea?
I guess a Love Parade isn't exactly to my tastes, but they seem to be quite popular. I prefer a centralized, weekend long festival over a parade, but that's just me. And I'm not huge on the techno/trance/electronica/etc. music, I like it better when it's blended with other genres (De La Soul's Troublemaker remix of Matt & Kim's Daylight is a good example).
I've been really interested in the concept of multi-sensory events recently, especially with all the hubbub over the Olympics and the X-Games. They do an excellent job of attracting people, investment, and media coverage that obviously benefits the city. The idea that an event doesn't just satisfy one purpose is also cool - the X Games have competition during the day, festival villages to meander, more competition at night, and a party throughout. We talked about getting an event like this in Boston, specifically an F1 race, a while back. I think it was either Ron or Beton that promoted it the most.
Either way, we need some type of event that puts Boston on the national map. Our sports are all well and good, but they attract only fans of Boston sports. Local live music is the same. People come from all over the continent to see Coachella and Austin City Limits. What if we could do that here?
