Boston got 6 inches or so of snow from late morning to evening on Thursday. There was enough snow on the ground that the evening commute was pretty hard, with loosely packed snow on the streets and a bit too much snow for safety on unplowed trails. I fell quite a few times, usually by trying to get back on a bikepath after riding off its unseen edge which was buried by snow or crooked plowing. By late morning on Friday, all of the paths were plowed with the remaining ice melting fast.

Please send updates and reports on the conditions of other paths in Massachusetts to Doug Mink dmink@massbike.org.

Arnold Arboretum 1.5 miles of park roads which are mostly closed to automobile traffic with no intersections Boston Parks and Harvard University	The main road up Bussey Hill from Bussey Brook is torn up for water main construction, so I've been using Walter St. and the paved shoulder of Centre St. to the entrance at the top of the hill. The park roads were pretty clear except for the sharp turn at the bottom of Bussey Hill which is perpetually in the shade.
Jamaicaway Bikepath 1.5 miles of mostly bike/ped-separated paths paralleling a busy 4-lane parkway; two intersections with traffic lights Boston Parks Deparment	This path was plowed once during the storm, though not always along the pavement, so I fell at least once when my tire got caught on the edge of the path. On Friday morning, there were firetrucks blocking the path (due to ice rescue training, I think), so I missed the ballards by riding the pedestrian path. On the way home, I had to deal with the mud around the bollards at Pinebank. The path was mostly dry by Friday evening, but really sandy.
Olmsted Park Paths 3/4-mile of mostly bike/ped-separated paths built over Riverdale Road, across Leverett Pond from the Jamaicaway. Brookline Park Department	It looked like at least the Route 9 end of the bikepath was plowed this time, though it never got plowed after the last storm.
Muddy River Path 12-foot-wide 0.6 mile shared bike/ped path with no intersections Brookline Park Department and DPW	Plowed to packed powder by Thursday rush hour, this path was really clear by Friday.
B.U. Bridge The bridge road lanes are narrow, and the sidewalks are wide and relatively unused by pedestrians.	The sidewalk was plowed clear by Friday late morning,
Charles River Bikepath Narrow, shared bike-ped path with few intersections Metropolitan District Commission	The MDC plowed the path by late Friday morning, though it was still really icy between the Riverside Boat Club and the B.U. Bridge Friday evening. I rode through, but not everyone would wish to.
Southwest Corridor Bikepath Separated Bike/Ped path with poorly-designed intersections Metropolitan District Commission	I didn't ride this path until Saturday morning, when it was plowed clear except for a number of places where snowmelt had frozen. By midday on my return trip, it was pretty clear.
Melnea Cass Bikepath Separated Bike/Ped path Boston Parks or Transportation Deparment	Not checked yet.
Neponset Trail Mostly paved Bike/Ped path Metropolitan District Commission	This path wasn't plowed, but discussions are under way as to whether the entire path should be plowed.
Cambridge Bike Lanes Striped lanes of varying widths on major and connecting streets City of Cambridge	Cars are parking further and further out from the curb with each storm, so bike lanes are less than their full width and should be selectively avoided.
Fresh Pond Bike Path Parallel to Fresh Pond Parkway in Kingsley Park City of Cambridge	Not checked yet.
Red Line Linear Park Over the Red Line from Alewife Station to Cedar St. Cities of Cambridge and Somerville	Not checked yet.
Minuteman Bikeway From Cambridge through Arlington and Lexington to Bedford Each town	This path is not usually plowed, except sometimes from Lake St. to Alewife Station.
