June is hot in the baltic states, can't comment on July and August.
The people are friendly. The Fuel is about half the price of the UK - about £5:50 a tank with my transalp (15 litres). The women are beautiful. Many young people speak english well. Food and living expenses are cheap. Might be worth a trip out to Saarama (sp?) - big island off the coast of Estonia. Watch out for the terrible roads in the east near the Russan and Belarus borders though. Great for a little while, but really tiring after a few hours and watch out for the rutts the trucks leave in them. I came a cropper in Latvia and ditched the bike. Nice local garrage helped me out though and I didn't even have money. Vilnus main honda dealer is useless. Was going to take two weeks to get a front tyre for my bike - so headed to "BolDor" in Warsaw for spares. They had most things in stock and gave a good service.
Ignor me please I crave attention - and white chocolate.
