Is there somewhere you would like to go and you don't see it on the schedule? Suggest it to the appropriate coordinator and consider leading it yourself. Leading a day or evening trip is reasonably easy.
If you haven't led a trip before and feel a bit nervous about doing so, talk to the coordinator anyway. We'll specifically pair you with an experienced leader. In addition, our trips typically have experienced Club leaders along for the event as regular participants, and many of them would be happy to give you a hand.
We are all volunteers, and all who lead trips now started by leading their first OOC outing at some time in the past!
