WOW!! Is Yosemite fantastic!! It took us about 1 ½ hours to get there from the campground and then I think it took us about an hour (traffic) to get to the entrance gate. From there, we drove to the Mariposa Grove where all the sequoia trees live. We took the tram up through the grove to the top but got out there and decided to walk back down. There are trails all through the area and the tram driver didn’t stop at the interesting trees long enough for people to get pictures. Luckily, even though the parking lot was over 2 miles away, it was all downhill and we really enjoyed ourselves…and yes, I was wearing my oxygen...just moseying along, enjoying the smell of the pines and being awe-struck at the massiveness of these giants, laughing at the antics of one little ground squirrel that Brenda gave some Frito corn chips to, and taking tons of pictures.
