Hunting for Amber (Vilnius)

So the long weekend is here. I want to go look for amber.... especially for amber with fossilized bugs in them.

Not sure if I can go to Klaipeda to the Baltic sea...Any other locations I can look for it? Like on the banks of the Neris in Vilnius?

Or does any one wanna go to the sea side for the weekend, I will be happy to share the fuel and other costs.
