Brownski, you can go ski in PA...but you need to have a negative test within 72 hours of entering PA, as per current PA guidelines that went into effect Nov. 20. Make it a day trip and there are few hoops you are supposed to jump thru on the NY side.
On the NY side, the quarantine and testing requirements instituted by NY in October were further clarified in a memo dated November 3rd.
PA is a contiguous state and travelers from PA (along with NJ, CT, MA, and VT) are not subject to the requirements. A NY resident leaving NY is subject to certain requirements, depending upon how long they were outside of NY.
To be clear, regardless of who you are or where you are from, you can travel anywhere you want....but you will have to fill out the traveler form and will be subject to a 14 day quarantine upon entering NY.....unless (meaning you can avoid the 14 quarantine requirement if) you fit certain categories....
1) You are a NY resident and you leave NY for less than 24 hours. No need for negative test to return, no required quarantine upon return. You do, however, have to fill out the traveler form upon re-entry and obtain a diagnostic test on the 4th day after arriving home. At least that’s what the current requirements say you should do.
2) You are a NY resident and you leave NY for more than 24 hours, or you are traveling to NY from a non-contiguous state. Fill out the traveler form. To avoid the 14 day quarantine...get a negative test result within 3 days of arrival, quarantine for 3 days after arrival, get a negative test result the 4th day. Do that and you are free and clear. Don’t and quarantine for 14 days.
The PA requirements are worse in some ways, but better in others. Generally a 14 day quarantine requirement upon entering PA unless you get a negative test within 72 hours of arrival. Worse in that there is no contiguous state exception from PA testing or quarantine requirements. Slightly better in that if you get a negative test within 72 hours of arriving in/returning to PA there are no further requirements, unlike NY. Failure to comply with the PA guidelines only threatens a fine of between $25 and $300. NY threatens much greater fines, potentially on a daily basis.
