2021 Convention: Washington, DC

organized by George Groth

From NPL President Jeffurry
April 1, 2021

WashingCon is still scheduled to take place July 1–4. We hope it does! In this year of continued uncertainty, we know that plans might change. We also know that due to emerging variants, varied policies regarding vaccination, uncertainty about vaccine effectiveness, and other factors, each of us is making our own calculation as to our likelihood of attending the con.

(pre-con event: June 30)
Westin City Centre, Washington, DC

Announcement from George Groth

The convention will be in downtown Washington DC. The dates will be Thursday, July 1 until Sunday, July 4. Washington is well-known for its Fourth of July celebrations. The Mall hosts the Smithsonian Folklife Festival and there are concerts and fireworks. I have booked more “shoulder dates” for those who will be arriving early and departing after Sunday.

Convention Drop-in Policy
Locals can "drop-in" for a single session Thursday or Friday night without paying and we encourage local puzzlers considering membership to do so. Thursday and Friday night sessions start at 8PM. If you like what you see at the session, it may be possible for a local person to join the League and pay the con fee during con, in order to attend the rest of con. If you are interested, contact the con host, George Groth.

Code of Conduct
The organizers of this convention are committed to preserving a welcoming and respectful environment for anyone who wishes to participate. We do not tolerate harassment of convention-goers or League members in any form. If you feel that any individual is speaking or acting inappropriately, either toward you or to someone else, please contact a member of the Code of Conduct Committee to mediate or intercede, as necessary.
