frog gigging

So…my son (8 yrs. old) has been watching a Utuber who hunts, fishes, gigs, etc. and got him interested in frog gigging. I got us a couple of gigs and we have been out twice to family land with a cypress swamp and gigged just a couple of not too big frogs. But it was pretty fun and he/we want to take it to the next level. Our property appears to have no bull frogs and getting around in the swamp isn’t easy. Anybody have any suggestions on where to take a boy to gig a few bull frogs without too much difficulty in the Charleston or Berkeley Co. area?
