Vancouver

Sept would be a perfect time to visit the Okanogen valley. The wine grape harvest should be in full swing to nearing the end. Meaning lota of stuff to see and do. Vancouver proper dies not have a good road system. Most trwveling is going to be on surface streets.

Here is a park with camping just north east of Vancouver. A friend likes it but I haven't been there yet.

Rv parks are outside the city. Do not go into the city with your rv. Traffic is hellacious. Congestion reigns supreme these days with the plethora of condos being built. Take the tow vehicle into the city instead.

Be careful in some areas of Surry. Lots of crime and drug gangs.

Stay at a good rv park and no worries.
