My church makes this trip every year, but I've never been able to go due to lack of funds. I would really like go on this trip because I feel that this is an opportunity of a lifetime to learn about Thai culture while providing service to their community and ministering to the women.\r\n\r\nThe total cost of my trip is $5000, but my church will pay half of this and I am responsible for the rest. $5,000 will cover my travel expenses and room & board for my two month stay in Thailand. Once there, I'll be sure to document my trip through a travel blog on http://thailand.adventures.org/. I can't wait to update my blog with pictures & videos from my experience and if you can't tell, I'm super excited about this opportunity!!\r\n", "headline"=>"Mission Trip to Thailand ", "category_id"=>"32", "goal"=>"2500", "expires_on"=>"04/28/2012", "rewards_attributes"=>{"0"=>{"description"=>"I will give you a personal thank you", "minimum_value"=>"10", "maximum_backers"=>""}, "1"=>{"description"=>"I will send you a personalized thank you & postcard", "minimum_value"=>"15", "maximum_backers"=>""}, "2"=>{"description"=>"I will pick out a personalized souvenir for you from Thailand ", "minimum_value"=>"25", "maximum_backers"=>""}, "3"=>{"description"=>"If you donate $50 or more you will receive a \"deluxe souvenir\" which is basically an upgraded souvenir from Thailand & an invite to the friends & family welcome back party!
