Sorry for late response, we were quite busy.
We didn't see as much as we hoped to see, because we were on tight schedule :) We definitly have to come once again. We saw Sequoia trees, stoped at the tunel view, went to Yosemite Valley. For lunch we had chili con carne which you recomended and it was deliciouse :) We didn't have time to go hiking so it was just a brief visit. Yosemite is very diferent compared with Death Valley and Grand Canyon and it's hard to rank - everything is beautiful on its own way. Thank you again for your tips and hospitality!
Kind regards from Slovenia! :)
