BankerJohn - when I switched from banker/lender to the head of marketing, CRA came along with the job. I didn't even know what CRA stood for and my predecessor left in a matter of 3 days and spent about an hour showing me boxes of CRA files.
I literally spent days and days reading those files, perusing various websites including FDIC and FFIEC. I called my local FDIC office and set up a meeting with their community affairs person. I looked at other bank's Public PE's (after I learned what the heck that was).
Then I found BOL, which turned out to be an incredible resource with people like Dawnie, Len and others, and especially Don Narup who was incredibly helpful and turned into a great resource from whom I had map work and demographic assessment work done.
Of course now, 7 years later, although I officially still hold the ceremonial title of "Chariman of the CRA Committee" (which includes Board Members), I officially got to pass off my CRA Officer title to seomoen else, and I very nicely passed along all of my files!!!!
