Long time fan of this site but first time poster!!

Taking my son down to Vegas first week of July. Won't make UFC 148 but could catch an open workout if it exists. Hoping some of you diehards can tell me how to find out if there is going to be one and if so where?

Also Insee that the fan expo is on for the day we are leaving. If you have been to one, are they worth checking out?

Thanks!!
