First of all, if you have kids, especially young-ish kids... You MUST check out Holy Heroes!
They have "Adventures" for Lent, Advent and Summer, and some pretty awesome products.
Catholic Icing has a cool Lent Roadmap (Calendar) that you can print out for Free :) and have the young ones fill out every day from Ash Wednesday to Easter.
Arma Dei also has an ongoing Lent Challenge that you can participate in for a Free product.
For a more "grown-up", check out the USCCB "10 Things to Remember during Lent" article:
In fact, the USCCB has many good resources.....
My plan this year is to get my "Spiritual Reading" on! I am committed to reading "Holiness: A Guide for Beginners" by Dom Hubert von Zeller, "Unbound" by Neal Lozano, and to at least begin reading "Imitation of Christ".
I know that since today is Ash Wednesday it is a little late for this, but this blog post "101 Practical Fasting Ideas for Lent" is awesome.
Have a Blessed and Fruitful Lent!
