We are planning an outdoor ceremony in February, 2012 at 5:00pm. I am concerned that the weather will be too cold to have the ceremony in the park the way we planned. We all know how unpredictable the weather is here in Houston but would you continue as planned and change things at the last minute if necessary or would you change it now - before the invitations go out? Please keep in mind that my Fiance is really set on the park venue. TIA
