you must focus on the other “free time” available and how you will use it. for now, a road that is covered by a roof that supports solar panels, or perhaps roads that are simply lined with solar panels could suffice. there is fun for all the family, and serious competition for the hot-shots. if you had to describe your music to the new colony on mars, how would you describe it? that aside, i read this post as being more than a tad troll-like. the last time the roof was done, i was picking up shingle scraps for years.
