Well, it's all relative. My HT location is in our greenhouse (16'x14'x9', mostly glass). That's also where the hottub is located. Since the room is otherwise full of plants and critters (some untentional!), there really is nowhere to sit, so the tub becomes the prime viewing location. If I'm alone, then I often use my pool floating chaise lounge in the tub (it fits!), grab a few beers and the remotes, and float in the tub while grooving to Rave or whatever. The screen is about 8' away, reasonable. I only need to get out to take a pi$$, and the small fridge is conveniently located right next to the hallway to the bathroom so I can reload on my way back to the tub. All is well, right? Most of the time! I often can enjoy this set-up only in the evenings on weekends, when I am otherwise exhausted from a long week or chores or whatever. So I have had a tendency to drift off to sleep in that chaise. You can guess some of the other things that have happened as a result! I have had to repair/replace more than one remote control that got an accidental dump into the tub, and after about the 6th beer spill or so, we're looking at a water change! I'm also afraid that the LCD screen will suffer from excessive UV exposure, so I devised a cardboard cover for it that I need to remember to put in place. I am also concerned about all the equipment operating in such a humid environment - in the winter after I have had the cover off for about 3-4 hours, it actually rains in that area from all the condensation on the glass. But so far, no identified problems with that. The 622 is its own heater, so I'm sure it keeps quite dry.
In balance, a good situation, but - alas - one that I can't enjoy nearly as often as I wish I could...
