Creation's Official Twilight Convention has several cities remaining in the 2010 tour as well as some in 2011.
See full listings on their website.
This weekend They are in Sacremento
and October 1 - 3 in Portland - I will be at this one and hope to see you there!!!
There are dozens of other dates. If you have not been to a convention (or even if you have) you won't want to miss it!
