This year’s installment of PorchFest will be hitting the city this coming weekend. Those who have, in the past, taken notice of the event – and it is an event that is rather difficult not to notice – usually have fairly strong opinions of approval or distaste for the goings on.

For the uninitiated, PorchFest invites local musicians to give something of an informal concert outside their homes, either on a front or back porch, yard, garden, etc.

The event is organized and presented by the Somerville Arts Council, who register participants and provide interested parties with maps to the “stars’” homes.

Some folks love it, others hate it, and of course there are plenty who fall in the middle. Naysayers complain that some of the participants get too loud, and that there is sometimes public drinking at certain locations that goes beyond legal limitations.

Everyone involved – performers and audiences alike – should plan their travels in advance and consider taking public transit, use the porta-potties provided, use the sidewalks and keep the streets clear, do not loiter and be considerate of neighbors and residents of the area. Also, remember that consumption of alcohol is prohibited. Tipping of the bands is also encouraged.

It is, of course, up to each individual participant to follow the guidelines and be responsible “promoters” of their own presentations. A few bad apples ideally shouldn’t spoil the entire barrel.

So, if you’re free for the day, you might want to take in one or more presentations at a porch near you. For a complete schedule of performances go to: http://www.somervilleartscouncil.org/porchfest.
