I haven't been playing for ages, so I've forgotten. Im trying to get to Lavender Town from Vermillion, and there's a sleeping Pokemon on the road. Signs say go through the Rock Tunnel (which I assume is the Digletts Cave). It's meant to be really dark, and you need flash, but I can see fine, and getthrough it fine, but the place I end up I the place with one of prof Oaks aides who gave me flash int he first place. Where's the Rock Tunnel, and how do I get to it?
