It's not just a trip that you should make some day, but that you HAVE to make. And sooner rather than later.
I go every year. If you go - take your wallet. Search the PowWow forum for denton or ETAR and you'll find all kinds of threads with pictures.
It's definitely a buyers shoot. Don't get me wrong, the courses are fun - but it's definitely the place to go if you have a shopping list (especially if that shopping list includes a new bow).
There's a group of guys from tradgang that go every year and shoot together, make sure to check around when everyone's making plans and I'm sure you can meet up with some if you were making the trip alone.
