Rattlesnakes

Thanks Mike,  I will make sure there are no sticks laying against the slide or under the slide for them to get any "ideas."

Now I gotta make a second movie: Arachnophobia II: PodSpiders

Fred, where do the scorpions fit in?  

Now you've got a winner! 😎

Late to respond here, but hope this helps - have lived with and camped with rattlesnakes all my life and a key thing is to be able to see where you put your feet and your hands. If this sounds really basic, it is - but it's often & understandably overlooked. So no criticism! I recommend putting a brightly-colored mat on the ground below your step (and in front of tent doors). This can be the bright green or bright blue indoor-outdoor "carpet" that you buy at hardware stores for example. It wil serve at least two purposes, keeping dirt out of your trailer or tent, and providing a contrast if rattlesnake/s are around. When you're ready to break camp, just sweep it off and roll it up. Anything that provides shade and/or cover - your trailer, boards or garbage can lids on the ground, tarps on the ground, wood piles, etc. - can provide for a rattlesnake. To them it's a shelter - they are hiding from overhead predators (hawks primarily) and also watching for their prey - so keep those kinds of things away from where you step, sit, reach and you'll greatly reduce the opportunity for them to cozy up near where you are. Always glance under picnic tables before you sit down for the same reason. In fact I like contrast under picnic tables as well :-)
