Just for everyone's info I just got done conversing with Tom at Hayseed about kits and shipping charges. If you order multiple kits the PayPal system will include S/H for EACH kit but as Tom pointed out there is a maximum shipping/handling charge of $10; until he can fix the web site system his temporary fix is to credit back the difference above $10 to the customer.
All this talk earlier about recapping got me to thinking about winter projects so I'm getting Tom's 2-B, 2-C, R-4C and T-4XC kits to add to the project queue for colder days. BTW, Tom has been off the list for a while but intends to return soon.
