Before I leave for any trip, I always make an extensive packing list. My standard packing list covers clothing, toiletries, and accessories for an extended weekend trip. Then, I have my packing list for outdoor trips, specifically fishing trips.
The detailed list includes: tackle box, tackle, lures, rods, reels, and fishing line, among other items. Then I have another list to cover items I need for my boat. Number one on that list is Mercury outboard oil. Yes, I’m sure I can get engine oil at a tackle shop, but I really don’t want to risk them not carrying my brand. I’m particular in that way.
