First time swimming USAS meet...nervous

Hi all, on Sunday, I will be swimming in my first USAS meet since I was 14. (I just turned 40). My husband (a fellow Masters swimmer and Stroke and Turn) thinks its great. My 8yo thinks it is so cool. (Could I freeze this moment in time?). I have gotten a lukewarm response from the meet director and it is making me feel as though I might be out of place/not belong. Any advice? BTW, the reason I am doing this is to get some NQ times in 200 stroke events. I live in a rural area and am having. Hard time finding masters meets this winter with the longer events, except for meets that conflict with my daughter's meets and/or are an 8 hour drive. I certainly won't win any events, but won't come in last either. I am afraid of parent's thinking I am taking something away from their children.
