    "I grew up here and actually bought my childhood home back after living in another part of the country . Beaches are close , most folks keep there homes well maintained . There are lot of children here and the schools are second to none . I wish the town would replace the roads here , and take better care of there pubic areas ! But let the young folks moving in fight that fight ! "

    "Crappy roads / rats / compact floresant lights instead of LED ( someone got paid off ) no trees left due to disease , and the town is not planting any ! Highway noise 10 lanes now on Sunrise HWY - RT27 . No plans for a sound wall ??? I guess we are lower class here in Islip . Airplane and helicopters all day and night fly over head ,, isn’t there a bay or ocean they can fly over then go straight up Lakeland Blvd to the airport ???? I will eave as soon as I find a house elsewhere and not in NY "
