Although we don't have the enormous fields you have in Tehas we do have some noisy ground cover. Have any used anti tracker footwear ? What you need is a light weight pair of boots some shag carpet & adhesive of your choice ,cut carpet an inch larger than your boot sole glue carpet to sole & vio la 75% quieter gate. Designed to leave no track but softens footfall. This idea was brought to you by a gent that is responsible for the total re vamp of a certain group of Navy forces in 70's & 80's . I use them often when stalking and they work. Regards
