When the Spaniards arrived on the coast of Florida in the 16th century, they encountered Timucuan indians wielding lonbows so powerful, that in one skirmish a Timucuan arrow penetrated a Spaniard's horse lengthwise from chest to rump. Yvsa's right as usual, indians of the eastern woodlands made quite extensive use of the longbow in hunting and warfare.
By the way Yvsa, I've got an Osage flatbow quite similar to what the Comanche used to run the Apache out of Texas. Apache weren't no punks, so them dadgum Comanche must have been some rough customers.

Oh, almost forgot to add, Lowe's sells the red oak in four foot lengths absolutely perfect for making kid's bows/short draw indian flatbows. At 2 1/2 bucks a pop, they're a dirt cheap way to practice carving and tillering bows. One lady in our group refuses to shoot with anything else but the ndn flatbow I made her, even though her husband owns a whole menagerie of bows. People look at her bow and think it's a toy or something. When that happens I usually borrow her "toy" bow for a second, step over to the shooting line, and start plunking arrows into the 40 yrd target like nobody's business. I'll hand it back to her with a "thanks, just checking my arrows", and they now see her "toy" for the ancient weapon it truly is ;-)
