RE: Back to WarmShowers - Hosting again before Touring again

The two are a couple, so they are traveling together. But apart from them there are a bunch of other cyclists touring Mexico (and the rest of the continent). Some of them are further ahead, others behind, some even go the opposite way. Occasionally they meet in person, if they happen to be close, but mostly they keep in touch over various social media. This way they can let other riders know where they have passed through, and whether they felt safe or unsafe. Clearly, there's never a 100% guarantee, but it helps quite a lot.
