Yup the weather's great now, it's late summer. The weather starts to be cold in early November.
As for Petra's relocation from the CZ, it's going to be interesting. Keep in mind that the main reason for the departure of Navratilova, Lendl and Hingis (the best three products of the Czech tennis system) was that Czechoslovakia was not a free country. For example, in an interview for a Czech magazine Hingis' mother said that she would have never left for Switzerland, had she known that the country would be free soon. She had very tough beginnings in Switzerland, I think she once also worked as a cleaning woman...
That said, even if the Czech Republic is now a free and safe country, moving to a warmer climate could help her.
For example, "it is believed that a contributing factor to Lendl's run of eight successive US Open finals and long record of success at that tournament was that he hired the same workers who laid the hardcourt surfaces at Flushing Meadows each year to install an exact copy in the grounds of his home in Greenwich, Connecticut."
I also think that her regular Turkey camp kind of satisfies the need for moving to and training in warm climate.
I thought she trained in Tatras Mountains in Slovakia (though I do remember her having a training in Turkey as well)? And I remember in the Tatras, they were dressed warm (probably for nice, cool mountain air).
So you're saying Connecticut is warmer than the Czech Republic (sorry for my ignorance)?
I had heard that story to about his tennis courts. Funny, Lendl is one of the few Tennis players that I heard, that lived in a relative northern latitude (outside NYC) while still active. Now of course, he could of had a vacation home in Fla.
Most of these Tennis players that claim their German, English, Russian, Serbian, or where ever, live in warm weather climates. I'll give you a few.
Federer-Monaco or Dubai
Azarenka-Monaco and Florida
The list goes on and on.
Of course some of these players live in these places year round, off season. But even if Federer or Murray spend time in England and Switzerland, their sure as hell aren't staying there during the winter, if they don't need to.
Petra doesn't have to leave, if she love the Czech Republic so much. She and her team just have to be much smarter with how she spends her time, especially when it's cold or if they think about her training in the Czech Republic (could be cold, Prostojev is indoors). That's all.
