indeed...drinking ice cold beer from my cooler in the parking lot is much less costly...lol...plus we have a stereo to listen to.
This is my routine every year since my g/f doesn't like to camp. A beer in the car on the way into the day parking lot, a few beers in the parking lot while meeting some new cool people, meet up with our friends at their camp sites and have a few more beers, enter the festival around 2 to see the first few bands/EDM artists that we want to see, then we won't drink again till the sun goes down. Medicating with some fine herbal is necessary a few times throughout the night, but not too much or we won't last until it's over. Then we repeat this routine again, then again, then again. Then on Monday we're hung over, exhausted, and sick and we know that we did Coachella right.
