Need some ideas for blues jamming

[MySweetFracture]

My cousin and i want to do some Blues jamming with my uncle (we are buying him a dobro for x-mas) And i wanted to know if you just could either give me, or direct me to a place that has more than just A,E,D jams. Im self taught, any help will do. I dont mind learing on my own, i just need some direction.

Thanks
