1. Ballast. Not really my favorite thing, especially in the early years
of flying. If for no other reason, if you do land hard, you have that
much more weight and inertia to splat you into the ground unforgivingly.
2. Catabatic flows. Quite often when evening flying, you may encounter a
the chance of a catabatic flow. Most often, even though you might not
know the exact direction of the wind, there are likely two primary
directions that it might be coming from. Up the hill, or down the hill.
Also frequently, these two 'opposites' might be less than 180 degrees
opposite and you can simply plot your final to split the difference
between the two wind directions. (Pine would be heading up the road
towards the mountain more or less.) If there is time and altitude, you
can alter your course more into the actual wind direction before
landing. A 90 degree cross wind landing is really only a zero wind
landing with a bit of sideways drift. If the sideways drift is strong
enough to be a problem, figuring out the wind direction should have
already been easy. Risking a zero wind landing with a bit of drift, is
(almost) always better that risking a downwind landing, or a quick 180
on final. Don't forget about the possibilities of using an asymmetric
flare. (Area B is an excellent place to practice that to the extreme!)
