ive been going to round valley alot to free dive latly if anyone interested in going let me know... i have boat and go often, weekdays are better for me but ill go on weekend if need be. water there is crystal clear and extra blue. im comfortable within 20 to 40 ft, but i go mostly alone so i dont really push it. boat only has 6 hrse. a little slow but still beats rowing. let me know. thanks pat.ps i have parking pass. if u live in nj ny penn area this lake is the clearest around youll love it...
