The important points are

- if this plant is an actual bamboo, that is a woody grass rather than one of the large weedy knotweeds often called bamboos by the uninitiated due to their having jointed stems (other true grasses, sometimes very weedy ones such as common reed may also sometimes mistaken for bamboos)

- if either of the two states involved have prohibitions against moving bamboos around, due to them being considered weeds like the knotweeds

- who owns the land where the bamboo you want is growing, and what they have to say about you digging some of it up

I don't know who owns the land. I don't know anyone who lives in Cloumbus GA. That was my first time being in GA. Some of the bamboo was growing on the road right-of-way

Call the State Highway Patrol and ask. Better that than getting arrested for trespassing on State property or for causing a traffic distraction.
