Things That Go Boom

 is a quest in Fallout: New Vegas.

Prerequisites
Ambassador Dennis Crocker gives the player this quest. However, the player must have completed the quest Ring-a-Ding-Ding, if not the option to receive this quest will not be available.

Edit - I have both quests active, (Ring-a-Ding-Ding! and Things that go boom) so the previous statement is false. (needs citation)

Quick walkthrough
Talk to George to place the bet and pay him 300 Bottle caps (or 200 with a barter check) for the timings to the bombardment. Go towards Nellis Air Force Base hugging the rocks on the left of the area to reach the Boomer base. Afterwards go back to George for your reward.

Detailed walkthrough
You will find an NPC named George. He tells you that he can give you instructions on how to avoid the Boomer artillery, but that it will cost you 300 Bottle caps. If the character passes a Barter speech check, you can buy it cheaper. However, George tells you this is not an expense but rather a bet, saying that if you make it there and back he will not only give you your money back, but also double it. Upon return after passing a speech check you can actually get a total of 700 Bottle caps minus what you spent.

The easiest method to completing this part of the quest is to tell any companions you may have to wait, and then run as fast as you can (or simply walk - worked on Normal difficulty) while hugging the canyon wall on your left side. This section can be frustrating, so if you keep dying set the difficulty to very easy, and you should be able to walk straight through without many problems. You also run faster without a weapon out (press and hold R reload). Make a dash for the fence, and head towards the entrance. When you get to the entrance, a guard will challenge you. Return to George for your cap reward. After this is completed convince the Boomers to help the NCR. []
