Good morning Andy,
sorry for the confusion but this thread is sort of old -- i.e 2 months ago we were looking at Syosset -- but actually ended up renting in Northport....

My current concerns are:
1) If I am to bike to Huntington, Syosset or Mineola, how safe it is when it is dark (or light ) ?
2) Where to leave the bike, once I am at the train station -- I understand that huntington has lockers -- but do they give you a choice which station you can have your bike stored at or may be I should get foldable and tag it along with me ?
3) If it is not safe -- is it a better option to drive to queens/ take folder on LIRR and bike from there

I guess I will have to figure this out once I am there -- I was just hoping there are people who already do it -- or want to do it as a group -- looks like I will be a pioneer.
