Here is my proposed design for the official logo of your camp site: #7. The most important thing is that this reflects the crazy fun you have, so I tried to toe the line between wild and fun, yet still professional looking. 'Organized chaos' if you will.
Oh, and the 2nd most important thing is that it looks awesome on t-shirts! So, I kept that in mind as well—something your friends and family would be proud to rock even when not camping. This current design could be made with only a 4-color print job: #8. I also added a grunge texture over the top to give it a cool vintage look. This can be turned on or off at the push of a button!
