I recently started a group on Meetup.com - so looks like about 38 people are interested in hoop meetups in my immediate area, and I started teaching a class at my city's adult ed. center - so another 27 people or so may be into it as well. I spoke with my parks and rec dept. and they are very strict about permits for any planned group gatherings. Have any of you had to get a permit to use your local parks? I'd love to hear about your experiences with this.
