Rain Man, you have lots of really nice bamboo there! Do look into curing and various ways of drying it. May even want to make yourself a long drill bit to hole through the nodes. This aids in drying and curing. But in the short term if you have anywhere to stand it up, barn or garage or basement, it helps keep it from warping.
Grab your torch or a fire and play with curing. Good Luck!
