Hopefully there are some nice coins there for you. Some spots are better than others and any spot is worth investigating. Yesterday the first hour for me yielded pretty much only junk but I persisted and it paid off. Once you get used to the detector and understand 100% what it's telling you you will find that you start doing a lot better.
Always ask yourself when starting at a new place, "where would be the best place to sit down", as that is where the most coins will be. Shade trees are great, small raised areas as they are usually drier than the small gullies where water runs off, on flat areas coins can be random and anywhere. I use Google Earth historical imagery also as sometimes it captures where people like to congregate.
