I got my mom comming to see me in Tx.. What do you think someone from Seattle would want to see?

Answer 1

Texas is an awfully big place (as any Texan will tell you), so it would help if you narrowed that down.

Some general things would be the historic sites (Alamo).
Texas has great barbecue, which you cannot get in Seattle to save your life.

With a specific place, might have some better ideas.
