Whole Foods is something like four to five miles straight down Fremont from our house. For those who don't know Portland, Fremont is a very straight two way two lane street with a few trendy-ish pretty nice little shopping areas, lots of nice houses, and a fair amount of both vehicle and pedestrian traffic. If I were riding my bike alone, I'd feel fine riding down Fremont, but there are places where it gets pretty narrow and crowded and I didn't want to ride the cargobike down it while also having to pay attention to the rest of our group. We opted for this route instead and added a little bit of distance to our trip, but overall I think it was much more enjoyable that way.
The ride to the store was pretty mellow and relaxed - sun was shining, not that many folks out driving the neighborhoods as it was mid-afternoon on a Friday - and the way home was alright too though it was near dusk and there was a lot more traffic (oh, yeah - and, for me, my bike was a lot heavier as someone had filled it with groceries when I wasn't looking).
One nice thing about having your non-bike-riding mom along on a trip is that after you make her ride about eight miles, she gets a little tired and slows way down on hills...and then you have a good excuse to circle around on the flats between rises and wait for her. Aside from a few breaks to do that, really just one I guess, and a few sections where my wife rode the cargo bike to see what it was like with a pretty good load, I managed to pedal all but one bit on the way home. There's a rather steep block - just to the west of the golf course/park if you're looking at the map - that I opted to walk the bike up (and by opted I mean decided to walk the bike up instead of abandoning it at the base because I certainly wasn't strong enough to ride it up loaded). I must say, it was not an easy push even; my wife took over for the last bit to see what it was like, and she struggled quite a bit.
All in all though it was really an enjoyable trip to the store - even my mom who was quite tired when we got back said so - but then it was an almost perfect day for; I wonder how much we'd like it in muggy summer weather or riding headlong into a wind driven rain on the way home.
