Should I attend a Basketball camp?
Of course there is no right and wrong answer to that question, but let me try and convince you why I feel you should.
First, the sheer amount of time you spend on the court during a camp. During a week long camp, I would surmise you would have the equivilent of a whole season of ballhandling during games. Not only are you having all this ball contact, but if it is a well run camp, you are getting immediate feedback on your game. 
Secondly, if you attend different camps, you get to see the various styles of the different coaches, much like will occur throughout your playing days.
Third, is the fact you will be trying out for teams with high numbers of players trying out for a limited number of spots. Why not give yourself the best opportunity to make the team, especially if some of those other players are spending their time at the beach.
Last, and in my opinion, certainly not least, is the friendships you will make. I know by the end of the week, most of the players that come to my camps have exchanged email addresses and Facebook info and plan to keep in touch, with each other.
Hopefully, I have given you something to think about.
