Hi, I would like to get some advice regarding carrying money when traveling to Kathmandu. I mean cash in excess of 1000 dollars. I think it would also help other people who have the same question.

I was wondering if it's safe to take cash with you in person (like in backpack) when going from US to Kathmandu. 
or would you recommend doing like Traveller's Check. If you do Traveller's check, what is the fee when cashing in in Kathmandu?

Or would you recommend something else. 

Thanks.
