Backpack vs Suitcase

When travelling overseas some people are unsure whether to take a backpack or a suitcase, so heres the answer:

If you take a backpack, you can carry it anywhere you need to go, dont come across like a tourist, but more like a 'traveller', more durable and tougher than a suitcase and you can always have your hands free.

With a suitcase you may not always be able to roll it, steps always prove tricky, they're harder to move in busy streets, its impossible to pull your bag though snow and rain and the handles are'nt always the best.
