Well, genius... it kind of makes a difference if you're camping in the mountains or by the ocean... but we can read your minds... can't we? This may come as a shock to you but I feel absolutely no compulsion to make sure you're adequately entertained. You're a perfect example of the results of parents overindulging the kids. Figure it out yourself since you're too clueless to even help people to help you.

Yes, as John Wayne so aptly said, "Life's tough and it's tougher if you're stupid.

Use shrooms or LSD. Nothing like tripping when you're out in the wilderness.

Go hiking. Hiking trails can be fun, some hiking trails have interesting things to see along the way. Go swimming, boating, or bike riding. Cook out go to the nature center.

bocce is fun, and you can play it anywhere

Only boring people get bored.

And bored people are boring. Take interest in the things around you and Hey!Presto, you are not only no longer boring, you are no longer bored.

Take a hike. Listen to the birds. Watch the clouds.

You think you "need" to be occupied and entertained all the time, but you think wrong. It's a bad habit to be constantly "feeding your ego" and a camping trip is a good time to become aware of that bad habit. Learn to be content instead of bored.

Outdoor sex is always a good way to kill some time. (if you happen to be that type of "friends")

So, it helps if you inform us the destination of your camping experience. In Colorado, you can hike to 14,000 feet; raft whitewater rivers; go digging for gemstones; visit water parks; go mountain biking; photograph wildlife; go snowshoeing into June; go backcountry skiing. In any camping area, you can spend time cooking; playing cards; kicking hackey-sack. YouTube may provide you with many other ideas.
