Yes, one of the legacies of having a boom/bust economy, is quickly moving from where things are in a rush and a lot of things get torn down, to suddenly having the economic climate change and new construction drying up.
One of the end results is being left with a number of empty lots in what would otherwise be high profile and good locations. This was especially bad in the early 1980's here and there are even still some empty lots remaining from that time.
Fortunately, we did not repeat this as badly in more recent economic cycles and we have gradually filled a number of them over the year, but it is one reason I am cautious about tearing down things. I would prefer we focus on filling the remaining empty lots. A gap toothed city is not as attractive as one without so many gaps.
