Investigate that strange noise

For the last few mornings I have been getting up and heading out to the Innotech Conference in Portland, Oregon. Although I noticed a rumbling sound each morning when I woke up, I did not think too much about it and carried on with my day.

Today, finally, I investigated the noise:





Yes, that is an excavator and there are even more loud construction machines next door.

I'm not sure which is more pathetic, the fact that it took me three days to figure out what the noise was or the fact that I had to look up what the name of the construction vehicle was.

(I would not of had that problem if I had a three year old in the house.)
