Son went to both SLE and NASS - and to the Marine Corps SLCDA (check this out if you have not). Highly recommend you do any and all that you can. You are making a huge decision and gathering as much information as possible will help you make an informed decision and have no regrets. Son initially had USMA as 2 to USNA. After SLE and SLCDA, he decided ground was better suited to him than sea and went to a 1a and 1b. Of course, with USNA going to Marine Corps is ground. But overall, USMA was better suited. Now a Yuk. During Plebe Parent Weekend in March of last year, I asked him eye-to-eye, (think Dad dead serious face) "are you doing okay." His response was "it's hard. but there's no place I'd rather be." Son is thriving. Get as much information and exposure as you can to make an informed decision.
