Racquet vs Car!
It is no surprise that a tennis racquet, or even two, will not compete against the weight of a car
After a tough match it is easy to forget where you put your racquets, so, I suggest the first thing you do is put them in your giant bag that can not be missed!
The other thing to be careful of is the carbon fiber that is now exposed! If this gets into your skin it is not a pleasant experience!
The best thing to do is go directly to the dump and toss them in! Don’t mess with them!
