Next week a friend and I are planning to go on a 2.4 mile hike for the first time in NH. We’re bringing my dog with us (the trail is dog friendly which is why we chose it). The trail has about 1,100ft of elevation gain. We are going to bring the obvious stuff – bug spray, sunscreen, water, a bowl for my dog, sweatshirts, and lunch (we’re going to take our time and stop for lunch on the trial). Is there anything else we should plan to bring in our small backpack (we’re only planning to bring one backpack and take turns carrying it)?
