I'm 80-85% sure that I'm going to Bonnaroo next week.  Never done the multi-day outdoor thing, so I need some serious issues addressed. (Expert festival goers like S. Dot Cell, Joey Marshmallow & bnyced0, I may be looking at you here.) Please feel free to include important things I forgot:
  *First & foremost, the showering thing.  I heard there's VIP showers or something like that. (If so, I'm willing to bribe somebody to get in them as I only plan on getting regular tix.) Then I also heard there are NO showers & only "sinks".  Am I gonna have to end up showering myself in the middle of a swordfight?

 The prospect of even going a half day w/o showering plus displaying the *ahem* organ in an area full of sausage doesn't appeal to me even a little bit, and is the main reason I ain't 100% on going. 
 *I Have serious iPod withdrawal issues.  I'm guessing it would be super dumb to bring it, as I'm guessing I there won't be a power outlet center. 
 *Heard they search you upon entering the venue.  Is this a go through your vehicle thing, a pat down thing or what?  I'm not too keen on being touched by unknown humans unless they wear a 34B or above.     
 
     *Me & my lady concert buddy plan on bringing a cooler full of bottled water, food (hot dogs & burgers) & a little Heineken.  Is this feasible or what? 
 *How hot does it get really?

  (100s??) I've heard it's unbearable at night AND during the day, so need feedback on that. 
 *What are the best times to get down there/leave??? Plan on getting there Friday, leaving Monday. 
 *Doing the camping thing.  Got the tent, grill, shade covers, etc. locked down.  Any other tips are apreciated. 
 *Please advise what other crucial areas I may have missed. 
 Thanks.
