Cisco ASA VPN problem

We have three sites.  Two remote sites (sites B and C) are connected to the main site (site A) using site-to-site vpn tunnels on Cisco ASA 5505s.  Site A IP net is 172.20.28.0/24.  Site B is 172.21.28.0/24.  Site C is 172.22.28.0/24.  At site A, we have two ASA 5505s installed.  ASA #1 is used for systems at site A to access the internet, and it is used for employees to remotely access the network using Cisco's legacy VPN client.  ASA #2 at site A is used for the Site-to-site VPNs between sites A and B and sites A and C.  All systems local to site A network can ping systems on both the site B network and the site C network. Systems on the site B network can ping systems on the Site A network, as can systems on the site C network.  Remote VPN clients receive a 172.20.28.xxx ip address when connected to Site A VPN.  The problem is that VPN clients cannot successfully ping systems in either site B or C, even when systems local to site A can.  We have set up proper routing statements on the VPN clients.

ASA #2 has to have a route statement for the range of VPn client ip addresses.
Example:
 route inside 172.20.28.128 255.255.255.128 172.20.28.x  < where X is ASA#1

I have been out with a death in the family.  Sorry fir the delay.  I will look at each solution in the next few days when I am at my client's office and see if I can get any of these solutions to work.  Thanks for your patience.

Adding "access-list split standard permit 172.21.28.0 255.255.255.0" and "access-list split standard permit 172.22.28.0 255.255.255.0" to ASA #1 took care of it.  Thanks for the help and sorry for the delay.
