Well, I bought my supporting membership for Sasquan. Couldn't make the WorldCon last year because the new owners of the newspaper where I worked at the time erased my two weeks accumulated vacation. I drove to WorldCon in 2013 since it was in San Antonio.
I should be able to make the WorldCon this year (and as I noted previously, I am on the program for the American Mensa annual gathering in Louisville, Kentucky.
For the record, I support the Washington. D.C. 2017 WorldCon bid.
