Are researations needed most of there time anymore?

Silver Falls is a nice park and a short drive from Portland - it's not representative of typical Oregon State Park. I never camp a SFSP without a reservation and often you have to make those well in advance. With that said - Oregon State Parks are getting more crowded every year - State has had inflow of people for a long time and word has gotten out that our State Parks are far superior to most. I never used to make reservations in the off-season but I suspect that's going to change.
