Pay off most of the debts, gotta keep a tax right off with the mortgage.

Put an addition onto the house for a bigger living room (20' x 26'). This would be timber framed like the old barns are. Finish off the exsiting basement with the two bedrooms that are currently planned and the basement in the addition would be finished off as the 'man cave' complete with a kick a$$ home theater system, rec room and an Irish bar for the family get togethers.

Build a garage to hold the vehicles and get some new toys. Like Pat, it will be some old muscle car classic iron.

Buy more land... can never have too much of that.

Spread the wealth by giving some money to family and taking a trip at least to Ireland with the wife's side of the family.

I am sure that there are more items but at least this is a start.
