Is this a spider that I should worry about?

Spiders are predators, they are good.

All spiders are good. 

Look up pictures of black widow, brown widow and brown recluse.  The last one is probably the most harmful if you get bitten.  If there are any other poisonous spiders in NY I hope folks will chime in.  Some people with kill every spider, snake and inconvenient creature without a second thought.  Be safe but also knowledgeable of the creatures in your living area and how to co-exist.

Thanks guys.. I looked at some sites but haven't seen this one. I'm glad to know they're on our side.

You should only worry about him if you're a bug. ;-)

Sal   I am sorry I have to disagree with everyone else.  This is a spider that I have found inside my screened pool lanai and one bit me when I didnt see him and I was removing dead flowers.  It made a dreadful wound and hurt for a long time.   I went through each plant and the ones that had a spider got a spray of bug killer late that afternoon.   All spiders that were throwing webs on the screen were smashed with my gloved hands and the ones high up were pulled down and destroyed.   I do the removal each day and there are hardly any now.  Will continue until there are none.  I figure I have a half acre lot and plenty of plants outside they can live on.  Just not in my garden and inside the pool area where I spend my time.    Hope you all still like me......Be careful Sal        Joyce

YES!! You should be very scared! I think you should send the Tree and Spider to me, He might bite you!!

Well the spider has moved on I guess. I just checked and it's gone.
