A fair proportion of my trips out are on the spontaneous side. I do have a list of possible destinations but the final decision is often made on the day, taking in what the weather is likely to be or what the travelling conditions could be like.
I know working this way is most the most efficient but on the day I don’t think I’ve lost out too much and there’s always the chance that you drop on an event that hasn’t been advertised much or not at all outside the local area. Like the Rush Bearing parade I caught in Ambleside. Many cameras laid in wait as the parade passed though the middle of the town, not the easiest of tasks in a popular tourist destination on a busy Saturday.
