One of the earliest and best rides to do in Spring is the Pipestone Canyon Loop that hooks up Lester Road and Balky Hill Road. You can ride from town, enjoy the interesting rock formations and flowers in the canyon before the snakes come out of hibernation. Even though the rim trail is unrideable due to slides, the unique geology of the canyon makes for a great ride.
My go-to product in Spring when things are still wet is the Muckynutz Butt Fender for $11.99. It's a quick and easy way to add a lightweight fender when you want to avoid that dirty strip up your back and it's no hassle to remove when it's dry.
