has anyone else taken an ipod or an mp3 player into the stand with them? this season i have taken my ipod and have had one earpeace in and the other peace in my shirt. i keep my volume at a minimum. havent had a problem being heard or spotted. personally, i think it helps pass the time and can help me stay in the stand longer. i dont have it on all the time buti do 30 min with one earpeace in and 30 min withit out.anyone else try this out?
