Ace with a weakish kicker short handed ( 5-10NL) whats my action?

[arod15]

5-10 NL 7 players (4 sitting out) so really 3 players

Effective stacks 1200
Hero is delt A [img]/images/graemlins/heart.gif[/img]9 [img]/images/graemlins/heart.gif[/img] on the button

Hero raises to 35
SB folds
BB re-raises to 70 (no reads on him yet as I just sat down an orbit ago and busted a shorti with KK. So I have no image yet)
Hero calls

Flop is A 2 7r (pot 145)

Villian Bets 250
Whats the plan?
