Where is Foster's located?

[Contemporary]

Here's what I know:

Address: 1123 Wilson Way

Most people think its located in Topeka, Kansas (since It was mentioned numerous times in that beach episode).

However:

-Spokane, Washington was only said in the beach episode
-Goofballs creators live in Canada (they couldn't of traveled this far!)
-The map that Nina shows in Good Wilt Hunting reslembles Neveda.
-In Bus the two of us, You see a broken sign that read 'New Hapshire'

So, where do they live?!

I'm guessing North USA
