Sadly it'll be best in Asia, but ok still in the US, not sure about in Europe.
The Leonids start at like 4 am EST tomorrow morning.... so either tonight or tomorrow would be a great time to go camp! You can look up on the internet when/if it'll be good for you.
Look for the constellation Leo, it should be there!
Also close to dawn (in the US) you should see Mars right near Leo (Saturn too) which could be cool to see meteor go right past mars
