Downloading footage we filmed in town on Mac

Today, we downloaded the footage we filmed at town on the Mac. The footage downloaded was 2 minutes 29 seconds from 31 clips. We realised that we needed more footage if we are going to edit our opening. However, we then noticed that it would be unlikely to film more footage in town as when we filmed in town it was raining and there were cars in our shots. If we had to film some more footage, it would mean that it would have to be raining on the day we film and that the same cars would need to be in our footage so the opening would make sense. However, this would be impossible as the surroundings in town would be different everytime we go and film. This means that we would need to film everything again on the same day and would need to film as much as we can and extra shots so that we would have more than enough to edit with.
