At this point, it looks like the answer will be "when I get another job." Bike shop hasn't done enough business to make the rent, and the weather isn't expected to improve much until after the end of the month, so likely we'll be spending a couple days packing up tools and cleaning the place out.

Unless anyone wants to buy a few rebuilt bikes. If I could net another $300-400, we might be close enough to get the landlord to wait a bit longer.
