Sg, how are you doing today? I guess I'm not going to get an answer to that question since you only logged in once when you joined on Friday and haven't been back.
I looked up Sonic in Seattle and we don't have one. You have to drive 20 miles to Renton or take a really long ferry ride up to Poulsbo if you want to get Sonic anything.
It's a little bit ironic if you realize that our NBA team that we used to have was called the Seattle Sonics. That would have been a natural merchandising tie-in, wouldn't it?
