Cowboys on Horseback

Mark,
Where are the Saymaly-Tash petroglyphs located?

About the petroglyphs in Alexander Stolbov's post -- any comments?

And what about cowboys, horses, and Scythians? What language did the
Scythians speak? Did they speak a PIE language or simply an IE?

When Mallory states that we need to keep the IE homeland within credible
boundaries, do you agree? After all, it took less than 100 years for
movement to spread from the eastern US to the west coast. A similar
time frame existed for population movement in Eurasia.
