Recently it struck me that in the modern, gridded city, you are probably never more than three hundred feet from a crossroads at any time.
But could you go down the block on a quiet midnight and call up one of the assorted deities you contact at a crossroads? Will any one do or do you have to find the *right* crossroads to invoke Hecate or Lucifer or whoever?
The obvious answer is, of course, to get off my lazy ass and start experimenting, with the occasional control ritual practiced as far away from a crossroads as you can manage. But, well, lazy.
