Construction sites are great for dust devil chasing, as are freshly plowed farm fields. As a teenager, I would often drive out on summer days around my hometown of Plainfield, IN, just to find them so I could watch for dust devils. I had more than one police officer, construction worker, and concerned resident ask me what in the world I was doing. I always just told the truth, and in most cases it was no problem. Once, however, I did have someone leave a note on my car asking why I kept parking in his neighborhood and walking down to this field. He left a number on the note to call him, so I did. It took me some time to explain to him what I was doing, but after I convinced him (I think), that I was not doing anything shady, he was amiable enough, and started suggesting other places I might go (maybe just to get rid of me, I don't know).
