I know exactly what you mean about stopping other activities and going through the group and the collection. It's a nice escape...and exciting when you find a new key. Considering the high cost of entertainment (and gas, and food, and just about everything else) these days, the RRs are a nice escape for the $5-$6 shipping cost.
What makes it a 1st class RR is 1st class participants -- thanks again for signing up.
