Any lessons learned for someone stationed at one post with duty at a different post?

1SG,  I'm currently stationed at Ft. Lee, with duty at Ft. A.P. Hill.  It seems to me to be kind of a good news/bad news.  Being away from the HQ can be nice, less nonsense and micromanaging, but it does have its drawbacks.  Out of sight out of mind seems to work both ways.  Sometimes issues are better handled face to face or hand carrying the paperwork.  On the other hand, with you working at a larger installation than my current assignment, I don't image you'd have the same problems we do.

Absolutely not...I was assigned to Fort Belvoir, VA with duty at Fort McPherson, GA and never had an issue.  Everything was handled locally, but you MAY be carried on two separate rosters.
