re: SECCG

Yes. You can get a reloadable breeze card for $2 or a non-reloadable paper breeze pass for $1.

When you enter the station you'll see a bank of kiosks against the wall, jsut go to the kiosk and follow the directions. Select breeze pass, and load it with 2 trips for $5 (it's $2.50 per trip). That'll get you there and back. You can use credit card at the kiosk to pay. Once all that is done you'll scan the breeze pass at the little entry gate then board your train. If you're coming from the south it doesn't matter if you get on red or yellow line, any train going north will work.
