Location with Largemouth bass

Had a great day fishing with a young man I met during the reel fun fishing expo at Walmart. His dad brought him in and we talked fishing and they invited me out to their lake to see what we could figure out. This kid was a trooper fishing for 7 hours in 98+ temps and boated this 4 pound largemouth. We fished Carolina rigs in 10-15 ft of water on a med/hvy 76 Enigma HPT rod and an Ardent Grand reel in 7.0:1 ratio. Line was 30lb test braid main line to a 14lb test fluorocarbon leader 3/4 WOO tungsten weight and a 5/0 worm hook.
