The disrespect being shown to cable locks in this and other threads is unwarranted. As an earlier poster did state, ones location should be taken into consideration. Personally I think the On-Guard Akita an appropriate level of security for use as the o.p. describes. Regardless of locale. In fact, at risk of jinxing myself I will admit that even after moving to the Portland metro center from an outskirt suburb 22 miles distant, I am not yet fully in the habit of using my U-lock, and several times have tied up with Master cable locks in the 3-pack. Not advisable, but the 15lb U-lock can be and often are, defeated, so do not be smug when using one. When I really need peace of mind because I am going to be out of sight of the bike for hours, I take the folder, and take it with me. I haven't been barred from a venue with my folder yet. FWIW.
