One of the best ways to spend your free time

In Lithuania we have all four seasons of the year, that are very different and beautiful in their own way. We usually have 4-6 months of warm and somewhat dry weather, therefore it is really important to plan your time accordingly to make the most of that.
One of my favorite ways to actively spend free time when it is not rainy is roller skating.
