Vietnamese business

Nha Trang, seaside resort, but I want to get out of the city and explore the surrounding countryside. I ask the lady who runs the guest house where I'm staying, whether she also rents motorcycles. Yes, of course, 50000 Dong per day, that's about 3 US-$. Just five minutes, she says...
within a short time a woman on a scooter (these small motorcycles, that run around 40 or 50 kms/h) comes along. "Here's your motorcycle", and she hands me the key... she's the sister of the hotel lady, or her cousin, or some other relative, or a good friend... it's her scooter, which she readily is handing over for some hours or a day, in exchange for 3 $... that's how Vietnam works: every guest house, every restaurant is also a "tourist office" or a "travel agency", they sell you bus and train tickets, book a boat tour for you, rent bicycles or simply know someone to gives you his scooter for a while. Everyone knows the whole other rest of the world, at least so it seems... Where are you going next, they ask you... oh, city XY, listen, may I recommend this hotel or that guest house, they are relatives/friends/acquaintances, you really should go there... one simply can't escape from getting asked every other minute about this service or that, a taxi or rikscha driver, the girls from the restaurants, asking you to come in, or the hotel staff, trying to sell you a ticket or a tour... sometimes it's tiring, but that's Vietnam...

Nha Trang itself is - well - not bad, but I'm also not really excited. Living in Barcelona five minutes away from the beaches, the local main attraction is not that interesting for me. Yesterday I got on a boat cruise, we went to some islands, did some snorcheling at a rocky coast with a lot of corals(very nice), visited an aquarium on one of the islands, had lunch on the boat (really good) and enjoyed the "floating bar": you had to go into the water to get the drinks... all in all it was a fun trip with some accompanying visits, really not bad...
Today I drove around on the scooter, and I just have to confirm what I wrote in an earlier post: the most fascinating of Vietnam is its countryside, the cities are mainly noisy and not too interesting, one simply should get out of them as often as possible...
The weather is still not great, often cloudy or rainy, but when the sun is out, it really is shining: although I'm well tanned already, I got pretty burned on the boat tour and on the trip with the scooter... it's middle of May, and if I'm honest, I should stay out of the sun for the rest of the year... just have no idea how to accomplish this...
