I work every other weekend so half of my Saturdays are spent working. My free Saturdays it all varies on what I do, my last couple of Saturdays have been spent setting up my tank. Otherwise may spend time with family or boyfriend, or getting much needed relaxation after a hectic work week.
I like to enjoy watching my tank on saturdays... about the only day I get to really spend more than just enough time to feed fish / check on things or take care of maintenance.
Sleeping in and relaxing until Noonish. If the weather is good, yard work. Bad weather, tank maintenance. Fall/Winter usually involves college sports. If there is still time, there is always something around the house that needs cleaned up, fixed, or improved -> the same goes for this hobby...lol
