You’ll be in my neck of the woods as I am 30 min from York and 1 hr from Lancaster Just on the MD side.
Do you have any type of business? EBay sales, Facebook sales, bake cookies, tutoring, etc. If so, the CIP (Chase Ink Preferred) is a great starter since it comes with largest bonus at 80k ($800 you could cash out or use their travel portal for a better redemption.)
If not, the CSR (Chase Sapphire Reserve) is a great personal card. It has a high AF but you get $300 travel credit and global entry (if that’s of any use to you). It has a 50k bonus that you get 1.5x when using the travel portal instead of 1.25 with the CIP or CSP.
There is also the ability to join Dischurners where’s lots of good info and the ability to support other Dis’ers.
Have a great time in PA and DC!
