TMC
I am probably only about 30 miles south of you and my LSU Gold was really good. I got mine from EL as a 3 gallon last fall. It will probably produce no more than 10 but I picked quite a bit off. My best one actually still looked almost mint green on the skin.
I pick it like I did as a kid. Soft when squeezed between index and thumb. Skin cracking is of no relevance. So far, when I waited for sugar spots, some have been over ripe-i.e. St Anthony's.
