Furthermore , the smaller of the two stages is covered so it has the feel of a more intimate club or concert hall . Really great atmosphere . I only attended the first day because I figured camping on my own for four days would lose its appeal quickly , however I 'd love to go back in the future for the whole thing . It stormed torrentially right in the middle of the day , but I managed to stay mostly dry and was n't too miserable . Thankfully , it was pretty much dry again by the time R.E.M.
According to the above context, answer the following question.
What can be concluded about this concert venue and the duration ?


The concert venue must have been outdoors and lasted 4 days .
