The park my fiance propsed to me at has a bandshell that would be beautiful for a ceremony, it is also less than 10 minutes away from where we are thinking about having the reception. However, we are planning on getting married around mid-October or even November in northern Indiana. Sometimes this time of year is really warm but others it can be really chilly. Would this be an okay option as long as we had some outdoor heaters in case it is as unpredictable as Indiana weather can be?
