Rainbow trout in its' natural environment

I was visiting Yosemite national park last weekend with my family. It's a great place to visit, though now it's been so dry that the Yosemite water falls looked like there's only someone pissing down from the cliffs :)
If you go there I can recommend the Yosemite View Lodge for accomodation although the prices are pretty steep this time of the year.
Up there I learned that the only natural fish in the rivers there is rainbow trout and that also only up to 1200 meters high. We saw one rainbow trout while we were wading in Merced river to refresh. The 30 cm trout slowly swam as close as 2 meters from us. I have to say it was really beautiful, nothing like the fodder fed fat pigs we are growing in some facilities and ponds in Finland and then putting to certain rivers for fishermen's amusement.

It's too bad I didn't have a chance to go fishing in Yosemite. I felt like the Merced river was calling for me to come and fish it. There were so many great looking places for fishing. I definetly have to try fly fishing in California now that I'm staying here for a little bit longer than usually. If anyone has any recommendations for good rivers, good guides, renting equipment etc. within 50 mile range of San Francisco Bay area please let me know. My email is markook73(at)yahoo.com.
