Thanks for drawing my attention to this thread.
I have a 12" Newtonian on a Dobson mount, and as a general rule I make a point of taking it out every night possible. However, the fact that I am not at our summer house every weekend (but almost), and the miserable Danish weather, has only made it possible four nights for the whole of the last season from September to April.
Light pollution has also caused a dent in the pleasure. When I first set a telescope up at the summer house, there were nights where we just were astounded of the beauty of the Milky Way, despite the light pollution from nearby towns, but now the best we can hope for is to be able to see the Milky Way at all, and we do not need a lamp to get around, even if we just come out of the house.
We used to ask the neighbours to switch off their lights, but it no longer makes a difference.
Still, a lot of things can still be seen, and the Moon and planets are always fine to show to guests.
However, it will take many years before Jupiter and Saturn return to our night skies before midnight.
The seeing is usually not so good, and it doesn't pay to use the larger magnification, but once in while there a nights where even my 6 mm eyepiece seems to allow for a closer look, and I am thinking of buying a Barlow in order to see even smaller features on the Moon that one evening every second year!
