Well, that works out.
Got around to dealing with my federal and state taxes. The result is that the refunds will pay for the new tires bought a couple weeks back and still leave a good chunk which will take care of most of my expected RCFM expenses. So that's one less thing to worry quite so much about.
And with that expected expense mostly taken care of I can concentrate on other things.
And speaking of RCFM, a couple things are already taken care of. Time off work for the trip has been taken care of and RCFM registration has been sent in. Now if the hotel reservation folks would respond so I know I'll have a place to stay.
