Two years after bombs killed three, injured more than 260 and rocked Boston to its core, the state has unveiled safety procedures for this year’s Boston Marathon.

Like less year, spectators are being discouraged from carrying backpacks, suitcases, coolers and large handbags near the 26-mile course, which has been designated a “drone-free-zone,” according to policies released by the Boston Athletic Association and Massachusetts Emergency Management Agency Monday.

Grandstand seats at the finish-line will require an invitation from the BAA and all people entering that seating area will be subject to security screenings. All bags may be inspected as well.

The official policy also frowns on “bandits” running the route – where people who are not registered as an an official marathon entrant run anyway.

“The B.A.A. reserves the right to remove any person from the course who is not displaying an official bib number from the B.A.A. is subject to interdiction,” reads part of the policy.

No bags will be allowed in certain areas near the start in Hopkinton, near the finish line or along certain parts of the course. Runners will be allowed to carry one gallon clear plastic bag for food items or sports drinks only.

 The 119th Boston Marathon is slated for next Monday, April 20.
