Donna and I were lucky a couple weeks ago while at the park with the dogs. We were walking back to the car from the water area where Willow was swimming when we came upon two people hunched over something in the trail. When we got closer, we saw a giant green caterpillar with bizarre head spikes. Everyone was afraid to touch it, because the spikes looked pretty nasty (an effective defense, indeed!). The dogs were only semi-curious, but we kept them away just in case. It was crossing the trail, one frequented by dogs and bikers, so the two people hunched over it were trying to protect it as it made its way to safety. I took a couple shots, which didn’t come out perfectly, but should still give you an idea.
