HobbesOnTour I'll be traveling in June. Apparently already getting hot in your part of the world (I saw 37 for sometime next week, hopefully an exceptional day).
WRT the sun, I always ride with long sleeves + gloves + lightweight leggins, so hopefully that'll be ok. Might consider riding at night if the weather becomes too hot.
My concern was more about water availability. If cycle.travel (osm) is accurate in its location of public water fountains, there should be no problem.
Thanks for your input
