We try to have as many as we can without it being every weekend. The O'Tooles trip will start being every year and maybe every half year. I think the Vic BBQ day will be a yearly thing too from now on. I'm sure there will be discussions about the "Middle Earth Trip" becoming an annual event to different areas/states. Just keep an eye out on the "trips" section and see whats popping up.
People put day trips and overnighters up as well so there is a fair variety.
