Yosemite National Park
In the spring when the bluebonnets are blooming. So beautiful. You definitely want to go before it gets too hot.
AHouston: What is your favorite restaurant in Houston?
Uchi. It's one of the top places in the city. It's sushi and Japanese fusion.
AAustin: Do I need to rent a car for a week in Austin?
I would probably rent a car. There are so many things to see you'll end up spending waaay more on cab fare. Having said that, the traffic in Austin is awful! But it's still worth every moment!
