Our guide Regis Sam N., was driver & guide - so he speaks straightforwardly and not facing passengers, as a guide would. No amplification either.
He speaks with a strong African/French accent, wearing a face mask and still has a CoVID plastic shield separating passenger seat from driver’s seat. The 2 rows of seats from behind him never heard his wonderful narration. He reads and repeats what he reads - meaning, he doesn’t summarize and fulfill colorful stories - you get dates, and more dates following by his contagious “amazing”.
I asked Regis, after our first stop at Capitol to return all vocal barriers including mask - he as I now learned, is owner of RSN. He is very accommodating, courteous, always willing to take photos, provides chips & water, and helps in and out of his Suburban. The vehicle can seat 6 adults - those furthest to the rear have the smallest windows.
The information would be best received by French speaking tourists and those who want straight narration rather than a commentary.
