They should be fine...I dont like shooting preserves but fun every now and then and I will admit they are reallly good for dogs ..........I have only ever hunted 2 preserves a few times .....Tobacco stik in candor....top notch, and Contentnea......I hunted contentnea once when i was a banker back in the early 90's with some of my co workers....everything was fine and the duck shooting was was funny if not spectacular because of all the ducks .............they should still be fine as they have been in business a long time....Mack
