On grandparents, gag reflexes, GPS and other joys of family roadtrips

We had the wheels, the time and we were missing one of my grandmothers, so my parents and Lil E and I took one weekend day to get out of the city and just breathe.
We loaded up the milfivan with kiddie DVDs, bottles of water, giant cups of coffee, and our regular battery of motion-sick-child gear -- Dramamine, a pile of towels, three extra outfits for the boy and one for the mama, and then a prayer for please God, if you have any control over the gag reflex, let it be enabled in these 2-1/2 hours to Indiana and then again on the return trip, particularly in consideration of the penance paid on our last visit to this grandmother when it took double-time with all the sudden stops to catch, clean up, change and clean up some more with a crying and miserable kid in too many gnarly gas stations. Then, like good little test drivers, we sat in our parking space for a half-hour trying to figure out how in the hell to activate the wireless earphones so that my dad and I wouldn't have to hear Handy Manny all the way to Indiana (it gives me shivers just to think about). That dilemma was followed by how to get the satellite radio rolling up front (and not on that creepy Hair Nation station and, for the sake of not murdering the retired folk, definitely not the Margaritaville station). That led us to a nice long discussion over erratic button-pushing to get my grandmother's address inputted to the GPS lady (who, by the way, began to sound a wee bit irritated by the end of the day, I swear).
