absence makes something something

Making my life a little "greener" isn't always easy or convenient (just ask Kermit) but sometimes it actually can be.
While packing for my long séjour in France, an incident from my trip to Korea came to mind... Shampoo. Specifically exploding bottles of shampoo. You want to bring some because you don't know when you'll have a chance to buy any, but you can't put it in your carryon anymore because of the liquid rules and then who knows how safe it'll be in your checked luggage?
So I've found a solution. Shampoo bars. Like bars of soap, except for hair. They're a bit pricier, sure, but they are supposed to replace several bottles. Best of all, I can stick them in my carryon bag. Haven't tried it yet, since I figured I would use up my liquid stuff and save these for France. Hopefully it'll all work as promised, and if so, they may be a permanent replacement for the ridiculous amounts of plastic I waste on bottles of shampoo!
One step at a time. I'm going to try to make this trip as earth friendly as possible - it's the least I can do after all the earth's done for me!
