active around noon? that is very odd...what time of year? august, sep., nov.? .. if during the hunting season you seem them reguarly visit a spring that is great!! i would 100% put up a tree stand, in the thick cover it is good to be above ground to catch them moving in the brush as they will focus on the ground very hard to see what is around...just make sure you have a good enter and exit route to and from the stand and place it in a good spot based on usual wind patterns in that area.....don't put up trail cams directly there but maybe on a trail leading to that spring so as not to spook the mature deer that go to the spring directly..
