While visiting Right to Play's programs in Africa, Petri hopes to inspire the troubled country's children and teach them the virtues of play. She will blog about her experiences for Fourth-Place Medal. Read on for her first entry on how she prepared for the trip and what she expects to experience.

I have been packing for my trip to Rwanda and Uganda for a few weeks now. Trying to navigate the complexities of traveling to a country I have never been to before. Realizing more and more each day, that I will be stepping into a world very different than what I am used to. Priority number one used to be having my swimsuit, cap and goggles in my bag; the rest if forgotten, I surely could borrow from my teammates.

Now, three months exactly since the gold medal game in London, I will board a plane and join a new team -- staff and fellow Athlete Ambassadors of the global organization Right To Play, in Africa to use PLAY to educate and empower children facing adversity. My swim suit will stay at home and instead I will make sure I have packed my tennis shoes so that I can join some of the nearly 835,000 children that participate in the weekly activities Right To Play programs offer, taught by local volunteer coaches. I have wanted to participate in one of these "field activities" after I heard Johann Olav Koss, president and CEO of Right To Play, talk about one of his early experiences in Africa.

I originally learned about RTP in the Beijing Olympic Village, where they had an informational booth on their global programs. Upon return to the US I signed up to go to an event where I met Johann. He told us of a trip to Africa where he observed the most popular boy in the village was the one who had a long sleeve T-shirt on. They soon learned this was because he could take this shirt off, use the long sleeves to tie the shirt into a ball which the children would then use to play soccer in the streets. All these children wanted was to PLAY.

After hearing this story I often thought about what my life was like growing up. Nearly every memory involved me splashing around in a pool. I started out as a swimmer and eventually was introduced to the sport I love, the sport that has changed my life -- water polo.

What if I never had the chance to play in the pool?
What if I never had the chance to play in the pool? I undoubtedly would not be the person I am today. I was very shy as a child. Being on the swim team and then joining the water polo team helped me come out of my shell. Taught me how to set goals, communicate with others to achieve those goals and then believe in myself by achieving the small successes that lead to my end goal. I had no idea that all of this was even happening because all I was doing was having fun.
