Geocaching for old caches in Sitka Event Cache

My adult daughter from AddAllFam in Canberra and I (Grumma BooBoo from DrewskiAndFam)  are cruising to Sitka on the Celebrity Summit and hoping to meet up with other cachers from the ship or locals who like to help out visiting cachers.  We plan to visit 2 of the oldest caches in Alaska.  We have rented a car and plan to get some bear spray for this adventure which we are quite hopeful not to need.  Anyone interested in joining us??
