Splendour of Yellow Stone National Park

Yellow Stone National Park and Grand Teton Park are amazing natural wonders.Kudos to the US govt to have mandated protection.The water,the craters,geysers are amazing.
It is a pity that many americans are not aware of this wonder.The flights are expensive.
I would suggest using GotoBus.com for economical packages(caution:be prepared for mandarin and english commentary)I strongly suggest visiting Yellow Stone at least once in your lifetime.
