One of the best shoots I ever had was when a buddy and I got in a drainage ditch between two fields that were full of geese. There were small bunches constantly trading back and forth between the fields. It was a pretty windy day and the sound of the shots didn't carry very far so we didn't spook the main bunches off the fields. It was the most fun I've had in a long time. We just sat there in the grass, talking and laughing and shooting. It was great. Towards the end we got pretty picky about which geese to shoot at because we had so many opportunities.
It might be hard to get something exactly like that but if you can find a field or water body with birds in it and then see where others are coming from you can get in line and usually get a few shots.
Also, if you find a field full of geese you can often position a guy up wind of them and then get someone else to spook them off the field. They'll go into the wind so the guy upwind often gets some shooting.

Look to find them leaving water and heading for the fields in the morning. They usually leave once it's light. Their not as early risers as ducks. They'll often leave the fields and look for water around late morning or noon so if you can find water near a field you might be in good shape. They'll head back out to feed in late afternoon then back to the main roosting water body just before dark.

When we were kids we hunted a lot without decoys, basically pass shooting and jumping fields and we got quite a few birds. Windy days are great for pass shooting if the birds have to fly into the wind. My first goose was from windy day pass shooting. I sat on the front step after school with my shotgun as the geese headed back to the fields and a flock of snows came over fighting the wind. Right over the tree tops.
Ah, the good old days.

It can be done. Just get permission from the landowners.
Sometimes it's better than sitting in a field with a spread of dekes. It gives you a lot of potential options and you can always go where the birds are.
When you're in a field with dekes and the birds start piling into some other field nearby, you might as well pick up and go home. You may get a few stragglers, but not many.
