Boom
Bob starts to run up to the pedestrian footbridge with the backpack.
"What are you doing?" Leif yells after him.
"Follow me!" Bob yells. He has decided to choose the Mirage hotel which has volcano display with the fountain, directly right across the street from them.
Bob is fast, he has already climbed up the steps of the footbridge and now on the deck section of the bridge that overlooks Las Vegas Boulevard. Bob checks the clock.
30 seconds left.
Leif is finally climbing up, he is panting hard. He is now also on the deck of the bridge.
"Come over here," Bob waves.
Leif jogs over, "What do you want?"
"Do you see the volcano display and the fountain pool?" Bob points at the tourist attraction in front of the hotel
"Yeah."
"Throw the bomb into the volcano."
"You crazy? There are people there!"
There is actually a show going on right now but about to end, and the fake volcano is actually making sound and letting out steam.
