The correct answer to this open question is the following.
Although the question does not include the concepts covered in chapter 9 or any other reference, we can comment on the following.
You would typically plan your daily rides and hikes in the morning hours to minimize the chances of being caught in bad weather because in the month of July hiking and biking in the Rocky Mountains, in the western US state of Colorado could be a great experience during the mornings but there is a high risk of thunderstorms in the afternoons and nights.
In the summertime, warm weather facilitates the chances of lighting in the Rocky Mountains. And as we know, thunderstorms are very dangerous if we are caught up there in the mountains.
Experts on climate affirm that every year, almost the area is affected with 25 million lightning strikes that have caused injuries to explores and hikers. So if you are visiting this area during the summer, you better organize your activities early in the morning until two or three in the afternoon.
