Those are the two areas closest to MHC that I've fished (from kayak both times). For the Haystacks I launched from the public ramp at Turner St and W. Beaufort Rd on the Beaufort side of the bridge. There's a big marina there so plenty of water for big boats. Cross a couple of ICW channels as you head back toward MHC and you're into the haystack area. Some bigger creeks running through the marsh where we came across folks in power boats sitting in the deeper holes....As far as where to go, there are the haystacks on the other side of the high rise bridge between Morehead and Beaufort as well as behind Shackleford banks.
