Chasing Summer via Bicycle

I'm raising money for a cycling tour though Central and South America. My heart has been calling me travel and I'm finally at a point I can do it. In a few weeks I’ll be catching a flight to San Diego and meeting up with my buddy John. From there we’re headed down Baja kicking off what I hope to be the trip if a life time. I plan to post to my blog and social media along the way. It’s going to cost about $80-100 a week to stay on the road. I have been saving for this trip for sometime but haven't saved enough to make it to Paraguay. I'ed like to stay on the road as long as my budget allows. I already own all the gear and will be using the money mostly to buy food along the way. Anything you give will be greatly appreciated.
