dividing & travelling with a bulb

My friend so kindly is letting me take home part of a ginger plant that landscapers put in, and I was hoping someone could give me some tips. I've grown ginger before from roots I bought at the grocery store, cut and then let dry before planting... is it a similar process after digging up a plant? Do I have to let the bulb dry before replanting her plant? And how should I transport the bulb in my car for the 8+ hours in which it will stay in my car? (I'm pretty sure I shouldn't wrap it in wet paper towel, but I don't want it to die either.)
I'm also bringing home lots of cuttings, but I've done that successfully before :)
Anyway, any tips would be greatly appreciated!
Thanks,
Gina

If it is on active growth, try to take some soil with it's roots in it. It may help to cut some of the canes/leaves off so as to reduce burden on the roots. Keep it moist and don't let it toast in the car with windows up in a parking lot. Take it and it's glob of soil and wrap with a plastic bag. The rhizome/roots ought to grow in your yard even if the leaves die from shock in transit. Plant it where you want it permanently as soon as you can. I hope this helps, good luck. Also try the relatively new Ginger forum.
