Honestly I am having con withdrawal after Sakuracon. Just found out about Fanime and I really want to go. But most of my friends don't like anime and the ones that do are too poor to go. So just seeing who is out there I could possibly become friends with and go to Fanime with. For Sakuracon I actually went alone because my friends all could not make it. However I was able to meet some amazing people and had a blast.
Aw man con withdrawals suck :/ but I'm pretty sure you can find people to Fanime! Just hit up some of the gatherings!
I live in the Portland area. I also know A LOT of cosplayers (pretty much all my friends are cosplayers) that live in the beaverton/hilsboro area.
I also live in the Portland area (friends with Nikkiolie). Hillsboro area here!
