Is Northwest Arkansas a bubble?

[Zachary Stanley]

Would like some opinions on if anybody else thinks NWA will be insulated from the change in tide of the housing market as of recent. Living here I always here something along the lines of... "Oh we have Walmart, Tyson Foods and JB Hunt. It will slow down here maybe a little but still stay a hot market because NWA is invincible." 

Does anybody else have thoughts on this are of the country for the coming months? 

I of Course have my own opinions but want to hear what you all have to say.
