Welcome Nomad, and nice to hear of your fortuitous windfall!
Perhaps one or two of your local banks offer a "rewards" checking account? There are a few in my parts that offer upwards of 3.00% interest with certain conditions, i.e., having one direct deposit and 12 debit card transactions per month.
Going for the bank bonuses is a great idea. Check brokerage money market accounts too (Etrade, Scottrade, Schwab, etc); they sometimes offer even better bonuses.
You could also just stuff a pillow case full of one's for s's and g's. ;)
