I work and live Brisbane Australia. I love it here but I can't stay still for very along before I get the travel itch.
Traveling and football (soccer depending on the part of the world you are from) are my 2 passions in life. I spend all my weekends watching the Brisbane Roar or planning my next trip.
If you need some postcard ideas I love pictures of cities. My favourite thing to do in a new city is go to the top of the tallest building and look down at the city. Postcards of the team you support would also be fun.
I'll really be happy with any postcards but here is a list of ideas.
-Postcards related to the place you are from
-Your local beer
I find the hardest thing is knowing what to write about. If you need guidance like I do then I suggest writing about your city, your travels or how you support your sports team.
