Wanna have fun traveling in a nice Clamshell/Gumball world in Frederick MD?
The clamshells are found on wooden poles all over downtown Frederick (and there's probably like a hundred scattered along with cobraheads....) most have either MV ballasts with retrofit HPS for MV ballasts and series remote ballast HPS ballasts.....
Have ride around Frederick starting
here Please keep in mind there's more than meets an eye! There are many brands and style of those clamshells in those areas......they are on many roads......
You may even notice a lot of the cobraheads have remote ballast too!!!
Enjoy!
