As noted previously, my page consists of the
aggregation of my various feeds and in working on that code recently it was again brought to my attention that everyone has different ways of representing tag metadata in feeds. I made up a
list of how my various feed sources represent tags and list that data here so that it might help others in the future.

South, I saw emergency vehicles lights on the North bound side and suddenly found my lane stopped. I found out why when a man ran from the left most lane to my lane the right most, then darted left
one lane and back right again. Cars started leaving my lane and I could see the man now lounging on the pavement in front of a jeep. Apparently not hurt, he got up and started walking down the
highway. He didn't appear to be in his right mind and after walking by our car Sarah reported it to 911. The rest of the night went on as normal and I had fun with Jon and his friends. It'll be sad
to see him go next week.

public political agencies.
