Melalvai, I didn't mean to rain on your parade. I'm sorry my first post came out so snottily. My comment was not because of your mention of them starting with $300; I went to the site and looked around some, and saw this:

We need your help to make it the whole 7,000 miles. We are looking for you to donate 5 dollars a month for the next 20 months.
That, and then the whole tone of their website, just rubbed me the wrong way. Kind of disgusted me, actually.

I originally had written more but decided not to post it, and will go back to my Growlery now!
