    Recalling a Beatles tune with a refrain of "Baby you can drive my car."
    No car, but a driver and that's a start. I have a concept but no Mark
    V...yet. It's on my wish list, and if I recall Alex does have one. Just
    a Celestaire practice bubble and a boy with a dream....
    Nonetheless, the principles are the same. IE and bubble/SIC error before
    any other directed play.
    Thanks again for the tip on the Uniden 250. Lots of folks out of stock
    then. Recently found one through Amazon for $70 ($90 MSRP) with free
    shipping. Everything I need included (without the usual costly "ups &
    extras" accessory list). 120V AC charger, 12V DC charger, belt clip,
    wrist lanyard, and cradle. I went with the white/gray 250G unit instead
    of the "serious gear" black model. Less heating in the sun and easier to
    find in a nigh time emergency.
