I have, also, seriously toyed with the idea of starting a obesity research/support foundation. That, really, would warm my heart, and would be the only way I'd consider monetizing the blog (to fund such a venture).
It's starting to become a good portion, yeah, used to be the majority was highway and MUP - but now I'm loving the limestone trails and gravel/dirt roads much better. So much more secluded, beautiful, and challenging. I thought gravel riders had a screw loose for the longest time, and I'm kind of right I suppose, but they also really know what's going on! It's a blast!
