Sidewalk Crest?

[PhoenixAzul]

What I've sort of seen in my travels is that Otterbein is a rarity. The crest thing is a pretty big deal here. Even non-Greeks know not to step on it ( I think the post man does as well!). It's usually on the walk leading up to the house. Ours gets repainted every year. For a while, there were no letters on the house, and I used to walk by and go, "What is that funny thing on the ground in front of that brown house?" (ahh freshmen year). I've been to places where groups have benches or something of the like painted with their colors/letters, or places where the pavement was painted for each group, but not a crest (I think that was Fisk, where the groups all had a section of the road in front of the student center/chapel). I know at my brother's college, they didn't do it. Just odd because I don't think this is an "Otterbein original"...just sort of wondering where it came from.
