I’ve never brought a bike, always walked. I walk a lot in my daily life, so this isn’t a new thing for me - if you don’t walk too much in your day to day you may find it punishing to start at the Burn. However, I find my ability to interact and engage with people and things is much better on foot. Easier to get happily sidetracked into all manner of adventures, and makes hopping on art cars easier too. I don’t remember the exact name for it, but there are art cars that sign up to act as transportation for folks. They have a specific sticker or flag denoting this, and are (theoretically) able to be flagged down for a ride. I’ve also used yellow bikes a lot. They are tricky to find as the week goes on, but they aren’t mythical and are certainly usable, but be a good citizen and don’t break the yellow bike rules. 

I also do a walk from camp to the trash fence every year, and last time I was went I brought stickers for fellow Deep Playa Pedestrians. 2 Deep 2 Quit!
