Here is an option. You guys can ride into town and stop by my place for a quick pit stop, pee, drinks, etc. I am about 10 minutes off of HWY 2 before you get to Airway Heights. Do a google maps lookup on E Tara Lee Ave, Medical Lake WA and you can see where it is. Then depending on where you are staying we can either head out to I90 or back to HWY 2. Just some food for thought. If needed we can also throw out a few blow up mattresses and have a futon that you guys can sleep on if you don't want to pop for a hotel room. Hell, I might even park the car outside so we can get the bikes into the garage.
