not me, but here's the shot I took during a flyover this spring.
NLXTACY- it's probably going to be a mad house up there if you hit it on a weekend, like any national park these days, it gets swamped. I presume you are the type to do a bunch of research on your trips based on your posts here

- I'd recommend taking as many back roads as you can to and from the area if you have the time; I'm biased but I think Oregon is the best state in the union for raw scenery.
couple links for you;
if you like trains or are traveling with someone who does (like my kids)
Train Mountain Railroad Museum and Gift Shop - Train Pins, Train Puzzles, Hobby Trains - Oregon
and if you have a bunch of time, or maybe something to think about for a big trip some other time:
Back Country Maps
and of course the
OR/CA- Jefferson State Cruisers - IH8MUD Forums are your local 'mudders if you need

and enjoy your visit to OR.
