Like building a wall, building trust is a process done brick-by-brick over many days, but destroyed almost instantaneously by the choice to apply neon wallpaper. Restore a partner's faith in your interior rectitude with today's Groupon: for $60, you get a challenge course Combo Day for two plus photos at Paradise Trail in Rhododendron (a $120 value). Your Groupon is valid either Friday, July 15, Saturday, July 16, or Saturday August 6.

Paradise Trail holds 23 years of trust-building experience under its harness belt, laying out a high-flying gauntlet of adventure on Mt. Hood that focuses on leadership, communication, and problem solving. The Combo Day begins at 9 a.m. and remains firmly grounded for the morning half, challenging participants to trust falls and extreme-trust tickle-sessions before breaking for a 20-minute lunch at noon. From lunchtime until 5 p.m., climbers take part in the course's mid-high (20'–40' off the ground) events, such as tree climbing and the high-ropes course. Once alighted, people smile for a photograph before opening wide for wind resistance. After returning to the ground, customers will have access to the photos online, so they can choose whether or not to display them on the family treehouse's fungi mantelpiece.
