Here's what I just carried home on my bike, 3.5 miles from the grocery store(s):
10 lbs Potatoes
2.5 lbs frozen peas
2 lbs cheese
4 lbs canned goods
4.5 lbs carrots
2 lbs celery
2 lbs bok choy
2 lbs cherries
10 lbs for a 12 pack of Sapporo
1 lb for cilantro, lemon grass, ginger root & limes
For a grand total of 40 lbs! And of course the part that's even better -- $41 was my total bill (just over $31 w/o the beer)
Woo hoo!
