Gwenevere is my fluffy white dog in a cat's body. She begs more than my dog does, she sheds more than my dog does, and she definitely eats more than my 50lb dog does. She's also quite friendly to the point where it's annoying. I jokingly try to give her away to anyone who enters my home but deep down I love her...(way deep down).
You're looking for a typical guardrail cache. There is plenty of space to safely pull off and park and the grass is nice and flat right in front of the guardrail. The trickiness of this cache is how creative you'll have to be to appear nonchalant. I was very sneaky about hiding it so you'll probably have to be equally sneaky to find it without bringing attention to yourself. It would not be the best idea to find this during rush hour.
Cache is a small pill bottle with logbook only so BYOP
