New here and asking for some sites and camping park recommendations. We are heading down from Vancouver Canada along the west coast (101 hwy) to Northern California then across to South Dakota where we are meeting up with a couple coming in from Toronto. If you have any recommendations or cautions would be greatly appreciated, thanks. p.s. we have a 30ft travel trailer (imagine 2600RB) and plan on starting our trip in May. Regards, Russ
