Just checked the boob tube and PBS has a 2013 special on tonight. The African Americans: Many Rivers to Cross. This one is "Into the Fire 1861-1896" about US colored troops. An hour show which also replays later.
Just looked at the boob tube schedule. A lot of tube and not enough ... Anyway the H2 channel has the last survivor show on at 9 central time which is just under an hour from now. It is a two hour show and I think it is the Frank Finckle docu-fictional-mentary that was done last year.
