Any advice on bicycling in a thunder storm? My friends and I have been planning a trip for almost a year. We are just now getting weather forecasts for the days of our trek (9, 10, 11 and 12 days from today). We will be riding 30+ miles per day on an abandoned railroad bed. Has anyone experienced anything like this that might be able to give us some useful tips? Any safety precautions that we should be made aware of? Thank you for any help that might come our way.
