Yep, I go almost every year. But then I also man our quilt group's booth.
The free demo's - classes are really neat. Do wear layered clothing as the classroom area isn't really heated and it can be cold with the concrete floors and all.
A friend bought a show sewing machine and got all the 'stuff' to go with it for a great discount. On Saturday the vendors want to sell what is left so as not to take it back with them.
Go with friends and make a day of it. I take my lunch because I don't want to eat the food there ... my preference.
Down here we also have the Tucson's Quilt Guild [in Tucson] show in January and the AZ Quilt Guild show in March. Lots of smaller shows too. Most are listed in The Country Register and flyers are at most LQS's.
35th Ave Sew & Vac has the largest fabric selection of any store in AZ. It is also worth a visit. They usually have sales during the Rusty Barn Promotions Quilt,Sew, and Craft Festival.
