Squashy Love

I mentioned on a facebook update that I was going to try 20 different squashes this season, so I figured I should update at how poorly I am doing.
To date I've had:
1. Kabocha
2. Butternut
3. Delicata
4. Acorn
5. Spaghetti

I have 3 more kinds at home, so I'll be able to add them to my list soon. I'm worried that I might not be able to find 20 different kinds.
