If I could travel to some locations alone, I'd be tempted to use a tripod and be very deliberate with my shots, using smaller apertures and longer shutter speeds. Mirror lockup and filters and the whole nine yards. But while my wife is quite patient with my hobby, the time needed for such precision photography would just create unnecessary stress, so better to avoid it. Plus as much as I always have great expectations of printing very large, I just never do. 8-1/2 x 11 on my printer if I print at all. So the need for high detail precision is really not there.

I'll retire 4 or 5 years before my wife does, so maybe then I'll squeak in some solo trips.
