April Fools Day sale It's supposed to be sunny and in the mid-70s on Thursday, so this sale couldn't be on a better day. (I hope the weather people aren't lying-it is April Fools) The Dairy Queen at 1512 W. Fifth Ave. will be having a special sale on Thursday. From 10 a.m. to 10 p.m., the store will be selling $.50 hamburgers, $1.99 parfaits, $.99 hotdogs and half-price cakes.
