I'm a very experienced traveller. I've already been to more than 10 countries around the world, travelling by caravan. Last time I was in [the|-]California and I want to share my trip plan with you.

I started my trip from [the|-]Grand Canyon. It's an extremely beautiful place! Then, I moved to [the|-] Hollywood. It is a neighborhood in the central region of [the|-]Los Angeles. I even saw Johnny Depp there. A few days later, I went to cool down in [the|-]Lake Tahoe. Also, don't forget to swim in [the|-] Pacific Ocean. There're a lot of cool places to visit in this state. Check my vlog to learn more!

Hi, everyone! I've just returned from [the|-] Washington, where I've found one amazing city bus tour. Thanks to this tour, I visited all the main attractions in one day.

So, I've been to [the|-] Cathedral Church of Saint Peter,[the|-] White House. Don't forget about [the|-] National Air and Space Museum. It has an incredible number of installations. Also I had some time left to visit [-|the]Niagara Falls.
