We chose an early 7:30am departure for the boat to Tallinn, which meant leaving our hostel in time to catch the 6:26am bus. I basically ended up sleeping almost the whole two hours at sea.
I didn't really know much about Estonia until planning the trip. My knowledge of geography and world events is quite poor, but I'm happy it's perhaps slowly improving as we travel. Estonia, Latvia, & Lithuania sit on the Baltic Sea. Estonia was ruled by the Danes, then the Swedes, then the Russians, then gained independence after WWI, only to be back under Russian power after WWII, finally gaining independence again after the USSR fell. Like many other countries under Soviet rule, the country didn't move much during those 40-50 years. Visiting Tallinn, you'd hardly know it. Some parts of it (the worn down buildings) reminded me of Bratislava. The old town is well-preserved and I think now being a UNESCO World Heritage site probably means they can't change it much. It was strange to see sometimes worn down buildings right across the street from seemingly newly-painted ones.
RS walk through the old town ^-^ We saw many tour groups during more than half the walk. In that way, it reminded me of Prague's old town center, except we only saw one Asian tour group. Considering these groups are probably doing a day trip just like us, it'd be interesting to see what the area's like at night, once all the day-tripping tourists leave. I'd imagine we'd like it ^-^ But, we didn't stay overnight.
The whole medieval theme is played up a bit. All the people selling drinks on the street are dressed in plain medieval garb, selling their drinks out of a barrel filled with ice. There's roasted, spiced almonds all over town with free tastings (a bit like what ginger snaps mixed with almonds would probably taste like), and these almond merchants are also dressed in medieval garb.

I loved this one exchange we overheard -- When asked how much the almonds cost, the merchant replied "We got a discount on today's batch, so it'll be two and a half rabbit skins. But if you don't have rabbit skins, gold coins will also do", as he pointed to the sign saying how many krooni.

We wandered out of the old town a bit, into the Balti Jaam Market behind the train station. It reminded me a bit of the Albert Cuyp market in Amsterdam; not only were there produce merchants, but also merchants selling clothes and household goods like soap, shampoo, etc. We saw a little eatery where we combined the 'what do you recommend' with point at someone else's dish technique to get a yummy meal ^-^ Large bowl of sausage and vege soup, chicken main dish, hearty meat dumplings, and pancakes came out to 98 krooni (~6 euros!). We also visited a bakery with possibly the lowest prices we've seen in all the bakeries during this trip.
Actually, the place we ate at was signed "kohvik", and according to RS, "Just outside the market at the end of the train station is Kohvik, an unimpressive-looking diner with a bustling stainless steel kitchen cranking out traditional dishes...", but we saw several kohviks. Apparently "kohvik" means "cafe" in Estonian O_o
On the boat back, I visited the 'supermarket' on the boat, which turned out to be similar to half of the duty-free shop on our Stockholm-Helsinki boat -- lots of alcohol and candy, and a few other snacks and drinks. The checkout lines were quite long.

Kids on slot machines? Whatever keeps them out of trouble, I guess.
When we got back to Helsinki, it was interesting to see all the people departing the boat with several Costco-sized boxes of beer and other drinks. Maybe the day-trip boat provides a bit of Costco substitute here?
And so, we're nearly at the end. We're flying back to Zurich on a 6:30am flight. There's still a few day-trips and a last couple of days in Ireland before we head back to the States. In one way, it seemed like it just flew by so fast. In another way, when I think about each place and all the memories, it feels like we've been traveling for a long, long time. Thinking about the end brings a touch of sadness.
