Reykjavik- Walk,cycle and boat

As we had nothing booked until evening, a lazy morning was planned. I still woke up fairly early (7ish) as it's very light by that time, though a cloudy day. Mom & I went down to breakfast about 8:30. She is feeling a little better this morning, but wants to spend the day resting.
I took the bus into town, and met Dorian & Jessie at their hotel about 11:00. They are staying at the Center Hotel Midgardur, a great location across from the downtown bus loop and at the start of the main shopping street,Laugavegur. We walked along this street to the old Harbour area with lovely restored buildings and lots of restaurants and pubs. By this time the sun had come out, and since there was no wind today, it's warm enough to sit outside without a coat. On the way back we stopped for an Icelandic hot-dog at the famous hot-dog stand (excellent , and very reasonable!) and walked back along the waterfront promenade.
Later in the afternoon I rented a bike from the hotel and biked for 2 hours along the waterfront past the domestic airport, a lovely residential area, out to Seltjarnes where there is a nature preserve and a lighthouse. Then along through the entrance to the harbour, the old harbour, through town past the lake Tjornin and back to the hotel. And except for a couple of block, the whole way was on bike path. A beautiful sunny afternoon, lots of people out.
For dinner, Icelandic fish & chips at a restaurant of the same name. It serves healthy fish & chips with a light spelt batter, roasted potatoes, and dips made of skyr. Delicious! From there it was a short walk down to our boat tour to see Northern Lights (hopefully). The boat heads out at 10pm for 2 hours. They give everyone "cruiser suits" to wear, which are nice & warm and have flotation in them. Not stylish though!
We were very lucky, the night was clear with lots of stars, and the moon not up yet. Just after leaving the dock, the Northern lights showed faintly. As we got further out, they became stronger, and started to dance across the sky. They formed a "crown" above us, and shimmered down. A wonderful show for about an hour. Then it started to cloud over, and we headed back to dock. A great experience! I didn't bother taking my camera, as you need a tripod & to be a better photographer than me to get pictures. I just relaxed and enjoyed the show. The tour company will send us some pictures in a few days.
