Went to the gun shop today by Willow Grove N.A.S. I figured out pretty quickly by the police every 100 yards along Rte. 611 that the Pres. must be in town. I'm not exactly sure how they flew a 747 over my house without me hearing it, maybe they landed from the NW which they rarely do. Anyhow, I made it to the light before the store when the police stepped out and closed the road. I really wanted to make it to the store, I thought if i'm going to see the Pres. it might be cool to be standing under the gun store sign. Instead saw him from a Mobil lot by myself. I didn't think i'd actually see him so I wasn't waving when they went by, but then there he was in the back window waving at 50 mph so I gave him a thumbs up. The lineup was, a state police helicopter, three state police motorcycles, a state police car, a limo, his limo , a van with side door open and obvious secret service, several press vans, an ambulance, and what I found interesting, three large windowless vans bringing up the rear with guys dressed in dark clothing and the side and rear doors open a crack like someone was holding them shut from the inside. Pretty cool thinking what they could bring to bear on a hostile target out of those vans very quickly. I was stuck there about a half hour. I was speaking to one of the officers and evidently they close the whole route he'll be driving before he starts. It makes sense but I thought they just clear the route as they go. My question is, does anyone know what they do with the limo's after he flies off? In hindsight I remember a C-17 landing there this weekend, which is rare for here. Do they ship them like that?
