No I dont know of steripens. I will look it up.
Indian Kashmir has soldiers outposted about every 100 meters.
It should be safe. How could I go to that neck of the woods and not ride the highest roadway on the planet?
Here's the link to the company... http://www.steripen.com/
I'm not a rep for these people, and I haven't used the product, but it looks like a good one for traveling as it's small and effective...and not that badly priced when you consider that you're avoiding being nasty sick.
