I can never under tourists who carry around all their belongings in a huge backpack.
Aside from looking extremely heavy, the climate here is very hot and humid, this will tire you out without carrying a heavy backpack.
Getting through crowds of people in tourist areas can be a real bummer, as can be stopping at a restaurant or café.
Backpacking is a lifestyle, but surely I would never think about trying this.
It just requires too much work.
How can you possibly enjoy Thailand carrying all that heavy gear around?
