If you are really loading up a bit, cross-section is pretty much impossible to avoid. The trick is to get comfortable with going a snails pace into a headwind, and enjoy the free ride with a tailwind...
Loaded touring really is about taking in the sights around you. You aren't moving fast.
One thing I would add, if carrying any substantial load, make ure you understand how your bike handles it. Your normal road bike isn't necessarily built to carry the rider plus extra weight/etc around the wheels.
My favorite parts of touring are the descents. Heavy bike go zoom. I take in the sights I just take in more of them in less time. Of course stopping when it makes sense.
