Personally, I try to avoid main roads as much as possible. I try to mix in suburban streets with sidewalks to get places. I feel that suburban streets are a safer choice due to having far less traffic and lower speed limit. I do not like the sidewalks since they're bumpy, but I rather shake my hands a little bit than go on the roads here. And when I do have no other choice but to share a road, I sprint it out until the next sidestreet/sidewalk.
I am pleased to see an increase of cyclists in the area and even some coverage.
