I have ~$24k in the NH State Retirement system, but I am no longer working there / contributing. I earned interest for two years, but now it's (way) past the time it's beneficial for me to leave it there. I'm very new to investing stuff and I am not sure what to do with it once I transfer it out of there. Is this something I should just roll into my company's 401k, or could I convert it to an IRA, dump it in a Vanguard index, or...?
