We get all of our egg or "sausage, ham, bacon and cheese" sammiches from the Carlisle High School Marching Band Support Booth. All net income goes to support this 300+ member, award-winning, marching band unit. The last egg sammich I looked into had something like three or four eggs in there. They are, indeed, a good buy.
There are other food booths (all very good) at the Carlisle show grounds, to be sure, but this is where we always seem to end up.
You can also go to the Pennsylvania Dutch, Greek Falafel, Roast Beef, hamburger, Salad or ice cream booths, and I'm probably forgetting another ten of them (like "Debbie's Hot Buns").
BTW: I think that Hank Ketchum, the creator of Dennis the Menace, coined the term "Sammich" back in the 1950's.
On the "Where should I get parts"? question, it depends on what you want to buy. I would find a copy of Hot VW's magazine at your local, well equipped book store and peruse the ads all through it. That should be a good start as to who is selling what, and you can ask us on here as to who's selling the better quality stuff for any particular part. Most VW parts I bought from Mid-America, SoCal Imports (although they may have gone downhill in quality lately), Cip1 and a few others. For genuine Porsche parts (get out your BIG wallet!) I went to Vintage Speedsters, Performance Auto, Automotion, Tweeks (now mid-America), Stoddard's and NLA. There's a long list of suppliers over on the other site under "Speedster Tech/Speedster Building and maintaining web sites"
Good luck....
