I did the NVOR back on 3/11.
You'll have a great time, but here are a few things to keep in mind to hopefully enjoy it a bit more:
-Check the weather and pack accordingly. March was really cold, but it is going to be inferno hot for the next few months.
-Bring 2 spill proof hydration vessels, 1 for water and for coffee/tea. You can fill them up at basecamp.
-The provided meals are actually very good, but the breakfast is basic.
-The general store at basecamp has some really cool merch, so be prepared to spend.
-Although a good portion of the session is driving, you'll also spend a large portion standing on uneven terrain, so bring good shoes.
-Think of a callsign for yourself before you get there. They'll ask you on spot, and if you don't have one, you'll end up with a number.
-I had prior engagements immediately after and did not pad enough time to enjoy the post dinner activities, so keep the evening free if you can. I regret to this day having to leave during dinner.
-Even if you may be a seasoned trail rider, keep your eyes and ears open because there may be new info that you haven't learned. My favorite part was learning how to be a spotter.
-You'll be able to choose between a large selection of Broncos, so try to pick one that is closest to your build. I have a 21 2D FE, but I ended up in a 4D WT, so there features such as SBD that I couldn't use out there, and the 4D handled very differently.
That should cover the basics. I had a blast, and driving a demo Bronco at the expense of another gave you more guts to get a feel of the capabilities, and boy, the Bronco does no disappoint. Be prepared to have a lot of fun!
