1. Be prepared for any weather
2. Camping might be rough
If you've never been camping, it might be frustrating that there is no air conditioning and you're with the same people constantly. It's just you, your car, your tent, and some friends.
3. Portable Charges are your best friend
If you even manage to get service in the camping areas, it won't be long until your phone dies. You will probably use your car to charge your phones and chargers as well, and your car will probably die. That brings me to my next point:
4. Bring Jumper Cables
5. Stay hydrated
6. DO NOT PUT YOUR WRIST BAND ON BEFORE THE FESTIVAL
7. Once you leave, there's not going back
Don't leave the campsite with your car. Whether you want to get food, or buy drinks, or whatever, if you leave, you're not coming back. And then you'll cry.
8. Mini propane tanks are awesome
9. Shoes are important
Bring your sneakers, and get ready to walk. The Woodlands alone is maybe 1.5 – 2 miles away from the campsites. The showers are a fair distance too. Make sure you bring a pair of shoes that you don't really care about, because they'll get wrecked. And make sure they cover your toes, people will be stepping on them all weekend.
10. It's all about the money
11. Life or death decisions will be made
Be prepared to choose between artists. There's a fair chance that there will be two artists you really want to see that are performing at the same time, and you'll have to make the dire choice of which to attend. It's best to make your schedule on the Firefly app before you get to the Woodlands.
12. Use the amenities, you're paying for them!
13. Getting front row is like the Hunger Games
There was about 90,000 people at Firefly 2015. For some of those big name artists, you will need to get there hours early if you want to be anywhere near the front.
14. You will become a lobster without sunscreen
Self-explanatory. You will hurt, a lot.
15. You will meet friends for life
16. Memories that last a life time
You will always remember your Firefly experience, and all the people you enjoyed it with. Taking a bunch of pictures and videos is cool, but the feeling of it all is unforgettable. Don't get sucked into your phone, enjoy everything happening around you.
