"...extreme care"

On being a Black Time Traveler in America's past. One would have to pick the place year season time of day, and location with extreme care. Unlike pink temporal travelers that can bungle into any era anywhere any time, and more or less not get killed.

Colored temporal researchers have to have rather a lot more care. For example I could appear on the above street safely. 9th Avenue/53rd Street in NYC. It's November 18th 1930 9:03/42 seconds pm. I could wormhole there, and explore the area with minor cautions.

Then again the Court House steps in Jasper Mississippi at noon on Jefferson's Davis's birthday in 1926 might be a serious problem. 

Walking while Black in any part of North America from 1609~AD thru roughly 2300~CE. This would be a life threatening though interesting adventure.

I'm thinking of spending the summer working on a science fiction story called "Black to the Future"

Sub-titled "Safety Precautions for the Black Time Traveler".
