For months I'd see him near the southwest corner of Madison Square Park with his buckets of soapy bubble juice and his bubble makers: several sets made of two wooden handles joined by a couple of feet of clothesline. He'd dip the clothesline in the bubble juice and create six-seven foot long bubbles. People, including parents and children would join him in the wonder of creating ephemeral rainbow bubbles.
Then I didn't see him anymore. I asked one of the park rangers I'm friendly with and he told me that some people complained - though I can't imagine what they were complaining about - and he was told he couldn't do it anymore. I guess some people can't stand seeing other people having fun.
