nice article out of Road Runner magazine, which discusses the pros and cons of riding with others vs riding alone. as an oft-solo tourer, I found the author's points relevant and resonant.
p.s. Road Runner is a mag I subscribe to, mainly to glean travel destination information. it's low key, 'family' rooted, and non technical, and over the years it has stimulated quite a few trip ideas for me... some of which I've done solo!
