You know that the Teathers 'n Feathers group, which is part of Black Rose
in DC has a lot of members in VA, don't you? In fact, I think that the MD/DC/VA
area is one with a very high concentration of kinky folks of all persuasions,
tickling included.
I'm sure if you planned a gathering, you'd get lots of interest. If you need
help with that, there are many experienced hosts who would be more than
willing to help you get that sort of thing together.
