This is how we left Nunu’s grave when we visited her a week ago.
I describe how to find it here: https://furtherdispatches.wordpress.com/2010/09/09/visiting-nunu/
So if you go looking for her, those flowers may be dead or gone but that Hot Dog should still be there so if you keep an eye out for it you may find it pretty easily.
You can also visit her “brick” at the Humane Society.
If you walk down the steps to the dog park and make a hard right you should be able to find it.
But if you’d just like to visit a spot she liked.
