One of the best things that ever happened to America, was the construction of the Great Stupa of Dharmakaya, about 45 minutes northwest of Fort Collins, Colorado. You can fly into Denver, and then rent a car. The stupa is tremendously powerful, for among other reasons, it houses the remains of Trungpa Rinpoche.
I think all of us should, at one time or another in our lives, make it a point to go there and pay respect. The photo above is of the interior, which should give you an idea of what awaits you.
Construction of the stupa took around seventeen years, and was financed in part by a wonderful benefit CD, donated by Sting, Joni Mitchell, Leonard Cohen, Willie Nelson, my dear, dear Emmylou Harris, and a number of others. If you missed the album, which I believe has been out since 2003, you can still amuse yourself and do some good by purchasing a copy. It is called The Great Stupa, and it is available in an enhanced version.
