If you're trying to escape the turmoil in Syria for the calm in Jordan, you have two choices.
You can go the legal way. Just get in a car and try to drive across the border. But that's not very easy these days. The Syrian government isn't letting many people out.
Or you can try the illegal way. Wait until nightfall, climb through a barbed-wire fence. It sounds dodgy, but if you make it over, you'll actually be welcomed by the Jordanian army. Troops will take your name, give you a drink of water, let you rest.
