I've been heading to UNLV football games and for a 46 year old stadium built in a desert, the Sam Boyd Stadium is A-OK...
Parking: Free Dirt lot parking for the games with a pretty close walk to the main entrance. The tailgating area offers a lot of space in a grass lot that makes for a fun tailgate experience. The UNLV vs Hawaii tailgate is always a great tailgate with fans from both sides having a good time before the game.
Stadium: As I mentioned it's 46 years old and you can tell. However like downtown Las Vegas, it's functional and you can still have a good time if you keep your expectations realistic. It's an outdoor stadium with minimal shading unless you're by the score tower with the sun behind it. It's bench seating that's not the most comfortable but I know that at every game I go to here. There's plenty of snack stations and I really try to avoid concession stand food so I eat up at the tailgate. $8 for a wide mouth bottle of domestic beers to keep your buzz going from the tailgate. Two major tips dropped there...=)
Staff: No issues with the staff throughout my visits and everyone I came across was pleasant.
As of Oct, 2017 there is a new bag policy that just about limits most bags, backpacks, purses, etc from entering the stadium.

Henderson police present was evident through the stadium along with the stadium security. Shout out to the men and women who help keep these events safe, much appreciated.
An old historic stadium that serves it's purpose and offers value for the football games as there really isn't a bad seat in the house due to it being a smaller stadium. Traffic isn't really an issue as it's away from the strip. Get a group of friends and you can have a really good time as I have. Enjoy yourself, it's a celebration! =)
