I hope you are taking #20 as far east as Omak/Okanagan? Then south to #2, which is just a great wandering drive. If you wanted to have some International travel, you could hang a left at Omak and drive up into Canada, then follow #3 right across to Pincher Creek, Alberta, turn south again, heading to Waterton Nat Park for a visit, then back into the US, to St Mary's and taking the To The Sun Highway, down into Glacier National Park.
hints...if you consider the Canada part,it is much prettier than the US routing, but, you require your passports to return to US. And no weapons into Canada. Yes...you 'could' take a shotgun but no handguns.
