St. Mark's has a very active youth program, tending toward the contemporary. My oldest went to a Steubenville Youth conference in Atlanta with them last month. Nice folks, solid theology.
I've never been to Mass there, so I can't comment on their liturgy.
So there's hope.
I've attended St Mark's once for a 1st communion service. As Anglo-Catholics, we have given it serious consideration as an alternative to the reformed AMiA, but it was unclear whether the clergy were in the Pope's camp or more aligned with some of the revisionist American bishops, and there also appeared to be little emphasis on the liturgy. I will visit some morning for early Mass and let you know if I get a different impression.
