I read an article in the American Chronicle about memorable Christmas gifts over the holidays, and I thought about giving a rafting trip as a gift. Amazingly enough, the article actual recommends whitewater rafting as one of those "unforgettable gifts" if you are looking for something truly unique.
If you think, it really isn't a bad idea. Events or activities are some of the most memorable moments in anyone's life, and you can give that as a gift. Depending on where you live or where you want to go, you can find rafting day trips for under $100 per person. Not too shabby for a whole outdoor adventure. Especially if you were planning on spending that much anyway! Rafting America has the complete list of outfitters, locations and information for trips in the US, Canada and South America.
