Flying in a cross wind

I went flying from Kendall Tamiami Airport today.  I rent my aircraft, a Cessna 172 Skyhawk, from Panair Flying Club.  I was doing touch and goes in a 15 knot crosswind on runway 9L (niner left).  That's not a big problem, but what made it difficult was the low lying scrub just above the N on the left side of the image.  What happens is that as the wind blows over the scrub it causes some nasty turbulence that makes landings tough.  I kept at it for an hour.  My landings did get progressively better.  When I called the tower to tell them I was coming in for a full stop I requested 9R (niner right) on the other side of the airport.  That made a huge difference in the quality of air I was landing in.  The field next to 9R is cleared which allows the air to blow smoothly across the runway.  No turbulence.
