Trying to find a better solution, I decided to try some new ways of
fixing the routes after the VPN is brought up. Heres what i'm using now:

I edit  /etc/NetworkManager/dispatcher.d/01ifupdown as follows:
Add the lines from "#vpn fix" to "#end fix" after the line "case "$2" in" as shown:

case "$2" in   
   #vpn fix
   vpn-up)
        #lets stick in a new host route to keep the VPN working
        DIF=`/sbin/route -n | grep UGH | sed "s/  */ /g" | cut -d " "  -f 8`
        DRT=`/sbin/route -n | grep UGH | sed "s/  */ /g" | cut -d " "  -f 2`
        /sbin/route add -host $DRT $DIF
        exit 0
   ;;
    vpn-down)
        #lets remote the unneeded route now that the vpn is down
        DIF=`/sbin/route -n | grep UH | sed "s/  */ /g" | cut -d " "  -f 8`
        DRT=`/sbin/route -n | grep UH | sed "s/  */ /g" | cut -d " "  -f 1`
        /sbin/route delete -host $DRT $DIF
     exit 0
   ;;  
   #end fix
 up)
	export MODE="start"
	export PHASE="up"
  ...
  ...

Now my OpenVPN configuration works with no extra routes set and no
options checked off. I can connect to all the hosts on the remote
network as well as use the remote gateway as my default (I push the
option on the server side) so I can secure all my activity while on a
untrusted hotspot.
