I was just going through posts to reorganize the opinion section of this site and came across this post from 2016. It’s a really great depiction of how ineffective the t-goins are. It’s an add on article for the recently written article titled, Honeymoon Island Beach Renourishment: He wants more, don’t give it to him. It was really only a year or less before all the sand placed on the beach dissapeared. T-goins suck!

From previous article:
