John, the spoke wasn't broken, but the
spoke nipple was, which would've been an easy fix if they had the right nipple size--just toss the broken one out and replace. But they didn't have the right size and the spoke cutter was not available because it is at their other branch until Friday. So bleh.
In any case, I'm riding the brommie over very short distances only (2mi and below) until the LBS can fix it, with no ill effects so far. Smaller wheels are stronger, right? Plus I'm not heavy...*crosses fingers*
