Hey Blanka. I missed this post and caught it a month late. I'm thinking about putting up all my reports on the Word Press Site I have (and never update).
I was a little disappointed by Yellowstone the first time I was there, but I'm coming to appreciate it. The crowds and lack of obvious hiking trails are what disappointed me, but the wildlife (and space for wildlife) and thermal features are what I'm coming to appreciate. I'd say do it. Also, Julie talked me into a few two hour lunches with a glass of wine (you'd substitute beer). Great idea. Sometimes just sitting and soaking in the atmosphere IS the thing to do.
Say hi to Kyle,
Jay
