Once in a Lifetime....
So I'm hiking the trail on the Brazilian side of Iguassu Falls and I pass the booth where they do the rappelling and it hits me, how can you put a monetary value on being able to say, "yeah, well I've rappelled at Iguassu Falls!" The rappelling trip and the pictures ended up being 100 Reis (about $60) so well worth the bragging rights to be able to say that I did it. I was expecting it to be a lot more and had planned on spending it. The whole decision part reminded me of the Brian Reagan skit about "Walking on the Moon."
Oh, and it was a lot of fun too!
