Space Gandalf

I began playing D&D and then AD&D back in 1980 or 1981 and continued until 1991 with a random game in 1992. Now, a quarter of a century later, I am getting back into it --thrilled that 5th Edition is much more palatable than some previous ones-- and prepping to run my kids (24, 22, 18, and 13) through their first adventure. I need to blow off some dust, break off some rust, and jump back into the realm.
