Filthy Fletch and all other readers, Maryland Hydro is for a fact under surveillance and works with law enforcement agencies. Being local and hearing rumors from friends I was amazed to find on google similar talk about the very popular store. If you type in Maryland Hydro on google you will find stories of arrests and investigations taken upon people that drove to the store and had been followed home. Some had their trash pulled, electricity bills monitored and their backgrounds checked. I'm just verifying that these are facts and you will be investigated if you go into the store in person. Some reports claim that the Baltimore swat was involved with the Marijuana eradication task force in a recent bust that started with an investigation at Mdhydro. Also investigations involving md hydro have led to at least 30 arrests and over 500 plants. I hope you 410 locals listen to this and spread the word because it may end up costing you or your peoples some time...matter of fact people everywhere should be aware of the law in shops like these. Perhaps the ones that seem leiget and professional are the ones being favored by law enforcements. Damn you really never know.
