Nox,
Put your 20 in, don't even think twice about leaving. It will be nice having that retirement check, money in the bank. Nobody is hiring, mergers in progress, age 65, etc. Timing is everything and now is not the time to get out. There is alot of unknowns, $110+ per barrel, chapter 11's. Whats oil going to be priced in two years? Stick it out, we'll know more about the industry in two years.
