    Subject: Still more arriving at Oshkosh
    Guys, Claude Tugwell and his EAA friend Don will arrive Sunday night by camper, driving from Amarillo TX. Sadly I have completed driving 1300 miles to Illinois ( in a day and a half) rather than flying. There were some nasty Thunderstorms, and to tell you the truth, I would have had to fly to Arkansas then up to Iowa to get into Peoria Ill. Nasty. I would have still preferred flying. Bud Yerly

    Bud and Europa Friends, Due to miserable weather forecasts for the return flight on Thursday & Friday combined with a mandatory social engagement in Denton on Friday night I will be driving up tomorrow and Sunday. Looking forward to seeing all the good Europa folks this week. Blue skies & tailwinds, Bob Borger Europa XS Tri, Rotax 914, Airmaster C/S Prop (75 hrs).
