Whats everyone been doing? i've had a hard time with mine so i slaved over finding something flintknapping in Nebraska and i came up with a blog. contacted the guy and has told me about the rock here... surprise! there's barely any! only Nehawk chert, (way tough) and niobrerra (rock?, yes i know my facts!
well kinda, its only by the river) hes hooked me up with a guy in my city and i will hopefully be able to meet with him or otherwise ask him questions.
