You will love Arizona in February..........not so much in July and August.
We live in the norther AZ area and my son that lives in Phoenix knows not to expect to see me down there in the summer months!
Arizona does have some awesome quilt stores all over the state. I'm looking forward to the show down there also

, as it should be comparable to Paduca, which I've never gotten to go to.
Enjoy your vacation and the quilt show!
