First of all, WTF is this thread doing in the waterfowl section? The mod should have been on it right away......
Have to agree with the Dude here. Be sure to evaluate the areas you intend to hunt with respect to it's use by non-hunters. Although it may be legal to shoot there, there's a lot more people out on dykes during the spring and summer months and some of them like to write letters to the local newspapers and contact council about shooting in these areas. It can lead to these areas being closed year round to shooting. Farms and private property will always be a better option if available and usually offer better shooting too.
Years ago I had permission to hunt a farm when the farmer was doing his haying. The crows were coming in to pick up mice and we got on their flyway and had a great shoot!
