It will be a very busy stretch for police and secret service as some of the 2016 presidential candidates make campaign swings through the Grand Canyon state.
Senator Ted Cruz's campaign has selected Arizona Christian University in Phoenix as an event location for Friday.
Campus safety and Phoenix police were performing walk-throughs and safety checks on Thursday. The campus activity center can hold up to 2,000 people with overflow expected outside the building.
"No backpacks, no bags, no signs, no posters, no poles, no flags," said Chief John Hoebee, with campus safety of Arizona Christian University.
Security will be tight. Campus police say some officers will be in plain clothes to add an element of surprise.
"We take it very seriously, we have police personnel on site as well as campus safety guards as well," added Chief Hoebee.
In Fountain Hills, town leaders are scrambling to pull together Donald Trump's event. Town leaders say they just found out about the event late Wednesday night. Fountain Park will host the rally on Saturday.
"We are securing all of the sites, we are looking at motorcade routes, we are looking at hotels at where these candidates maybe staying," said Cristina Beloud, Special Agent in Charge of the U.S. Secret Service Phoenix Office.
The Secret Service says they are stretched across the state at the moment.
"We have protectees, our candidates, in the state of Arizona from as far north as Flagstaff to as far south as Tucson," added Special Agent in Charge Beloud.
The Secret Service says supporters attending the events need to bring as little with them as possible. Liquids, except for water in sealed containers, food, most bags, chairs, pets and weapons are banned from all events.
"There will be lines, they will be asked to go through minimal searches of their person and other belongings."
Bottom line, if it can't get through security at the airport, don't bring it to any event.
Officials say parking maybe an issue, so get there early.
